Nursing home residents and professional caregivers may engage in behaviors that, although not considered formal treatments for depression, can improve residents’ mood. To support future studies aiming to explore ways to complement formal depression care in nursing homes, reliable and valid instruments for measuring these informal mood-improving behaviors are needed. This project developed and evaluated inventories to measure mood-improving behaviors in Dutch and Belgian nursing homes. Study 1 followed an iterative mixed-methods approach to develop two inventories: the Actions to Improve Mood by Residents (AIM-R) and the Actions to Improve Mood by Caregivers (AIM-C), and to assess their content validity (N = 31 residents; N = 35 caregivers, respectively). Study 2 evaluated test-retest agreement (N = 206; N = 125) and inter-rater agreement (AIM-C: N = 81) using a test-retest design. Study 3 explored the inventories’ practical application through semi-structured interviews (N = 12; N = 6). Data were analyzed through thematic analysis, content validity indices, and Gwet’s AC2 agreement coefficients. Both inventories demonstrated acceptable content validity, with moderate to very good test-retest agreement. Inter-rater agreement for most AIM-C items was classified as “fair,” and appeared lower when caregivers completed the inventories for residents with moderate to severe cognitive decline compared to residents with no to mild cognitive decline. Thematic analysis suggested that using the inventories increased awareness of mood-improving behaviors and contributed to better knowledge about residents. Challenges regarding usability and interpretability were identified, along with suggestions for refinement. The inventories appear to adequately capture mood-improving behaviors and show consistency over time. Nevertheless, their usability and interpretability could benefit from further refinement. Pending additional research, these inventories hold promise for assessing mood-improving behaviors in nursing homes, aiding future efforts to explore new ways to enhance depression care alongside traditional treatments.

OBJECTIVE:This study aimed to determine the effectiveness and cost-effectiveness of the Choosing Health program, which tailors support to an individual's weight loss and weight loss maintenance determinants among adults with overweight and obesity. METHOD:We conducted a randomized controlled trial with a nested interrupted time series within-person design. Participants (N = 288) were randomized to the Choosing Health digital intervention (n = 145) or a control group (n = 143). Intervention participants completed 90 days of Ecological Momentary Assessments, which were used to identify behavioral determinants to tailor an intervention. Control participants received nontailored weight loss advice via generic emails and eBook. Body weight (the primary outcome), blood pressure, and % body fat (secondary outcomes) measured at 3, 6 and 12 months were restructured into change of baseline scores and analyzed using multilevel regression analysis, with the three time points nested within subjects. RESULTS:Findings revealed no significant difference in mean weight loss between groups at 6 months, controlled for baseline (primary outcome; mean difference = 0.78 kg), F(1, 175) = 1.44, p = .232. Intervention participants had higher weight loss at 12 months than control participants (mean difference = 2.05 kg), F(1, 108) = 2.96, p = .088); however, the difference was not statistically significant. CONCLUSIONS:The results showed promising trends for the intervention group in weight loss maintenance measured at 12 months. The dropout rate was higher than expected, as the intervention was delivered during the COVID-19 pandemic making face-to-face assessments difficult.

In this cross-sectional study we investigated whether attachment orientation moderated the associations between sexual excitation and inhibition and sexual desire and arousal. A convenience sample of 358 participants (242 women and 116 men; mean age: 37.6 ± 12.0) completed online questionnaires including the Sexual Inhibition/Sexual Excitation Scales-Short Form, the Experiences in Close Relationships scale, the Female Sexual Function Index (women only), and the International Index of Erectile Function (men only). Associations were tested using multiple linear regression analysis. Sexual excitation/inhibition (sexual desire: BSES = .207, p = .044, BSIS1 = -.473, p < .001; sexual arousal: BSIS1 = -.419, p < .001) and attachment anxiety (sexual arousal: BANX = -.207, p < .001) independently predicted part of the variance in sexual desire and arousal. Relationship duration negatively predicted level of sexual desire (B = -.023, p < .001), while male gender positively predicted sexual desire (B = .634, p < .001) and sexual arousal (B = .487, p < .001). The associations between sexual excitation/inhibition and sexual desire and arousal were not moderated by attachment orientation. Further research into the interaction of sexual excitation and sexual inhibition proneness and adult attachment orientation as determinants of sexual desire and arousal seems warranted.

In this exploratory study of long-term romantic couples, research questions were: how does perceived stress predict positive and negative affect, and how do the latter predict emotional needs? Dutch couples reporting relationship problems after cancer treatment (i.e. clinical couples) were compared with community couples without relationship problems (i.e. non-clinical couples). Ten times a day for seven consecutive days both partners answered questions on affect, stress, and emotional needs. The actor-partner interdependence model was used. Stress differentially predicted positive and negative affect in romantic partners: while actors' stress predicted their own positive and negative affect, it did not predict affect in their partners. Independent of positive and negative affect, group membership predicted emotional needs in participants: emotional needs were higher in clinical couples. As expected, actors' negative affect predicted their own level of emotional needs across the board. Actor's positive affect, however, did not predict their own emotional needs, but specifically in the clinical group it negatively predicted emotional needs in their partners: lower actor's positive affect came with higher partner's emotional needs. Moderation effects of group and attachment orientation were found. The limitations on generalizing these findings due to small sample size and its specific characteristics are acknowledged.

Objective Previous studies have shown a positive relation between retrospectively measured loneliness and somatic complaints. This study investigated the relation between state loneliness and state somatic complaints as well as the direction of this relation in the context of daily life. It was hypothesized that there is a positive contemporaneous association between state loneliness and state somatic complaints as well as a positive bidirectional temporal association. Methods Using the Experience Sampling Method, 16 patients with somatic symptom disorder and 27 participants from the general population received a signal on their smartphones 10 times a day for 14 days to fill out an ESM-item on loneliness and two on somatic complaints. To test our hypotheses, multilevel linear regression models with random effects were estimated. Results Associations between state loneliness and state somatic complaints in the context of daily life were demonstrated (B = 0.12, SE = 0.01, p < .001). Temporal analyses revealed, however, that state loneliness (t-1) did not predict somatic complaints (t) in daily life (90-min window; B = 0.01, SE = 0.01, p = .573). Neither did state somatic complaints predict state loneliness (B = 0.02, SE = 0.03, p = .534). Conclusions This study demonstrated contemporaneous associations between state loneliness and state somatic complaints in the context of daily life. However, state loneliness did not predict subsequent state somatic complaints, nor did state somatic complaints predict subsequent state loneliness. Future studies are necessary to further disentangle the complex relationship between loneliness and somatic complaints.

Adolescence is associated with the onset of depression, with loneliness identified as an important risk factor. The present study examines both the contemporaneous association between loneliness and depression over time and the predictive value of developmental patterns of loneliness in adolescence for depression in young adulthood, thereby taking gender differences into account. Using 10-wave longitudinal data from the Nijmegen Longitudinal Study (NLS) of 128 Dutch participants aged 9-24, multilevel analysis revealed that loneliness is associated with depression both between individuals and within individuals over time. Further, the findings indicate that around 30% of participants consistently experience elevated levels of loneliness throughout adolescence, a developmental pattern that has predictive value for depression in young adulthood. Overall, consistent with the Evolutionary Theory of Loneliness and clinical theories, the study confirms a strong association between loneliness and depression. However, no significant gender differences were found in this relationship. Monitoring loneliness during adolescence may help identify those at risk and enable earlier, more targeted interventions.

Objective The present study evaluated the effectiveness of a new online behavioral intervention (Listening type Check) as an extension to an online hearing test, to increase safe ear- and headphone use and change the underlying psychological factors in persons 16–21 years old. Design An intensive longitudinal study with experimental design, using the experience sampling method, measured listening behavior and psychological factors two weeks before and after doing an online hearing test plus Listening type Check (intervention) or hearing test alone (control). Additionally, a process evaluation was performed. Study sample Persons aged 16 to 21 years living in the Netherlands and using head- or earphones for at least one hour per week. Participants (n = 54) were on average 17 years old, 57% was male, and 90% theoretically educated. Results Participants in the two weeks pre-intervention, used ear- or headphones for about 6 days a week, 2 h a day, mostly choosing a sound volume around 60% (on 0–100% scale). A loud volume (i.e. ≥60% when <18 years) was used for 40 min a day. These behaviors and underlying psychological factors did not change in the two weeks after doing the intervention. Conclusions Participation in a new online behavioral intervention plus online hearing test did not increase safe ear- and headphone use or change underlying psychological factors. Participants were primarily theoretically educated and exhibited relatively safe listening behavior at baseline, which may explain the absence of an intervention effect. A new effect study with vocationally educated participants or other high-risk groups is recommended.

Student mental wellbeing has become a growing concern in higher education, with increasing numbers of students reporting stress and psychological difficulties. Although academic factors, social environmental factors, and coping styles are all considered relevant, less is known about how these factors are interconnected in relation to mental wellbeing within a broader system. This study applied a network approach to examine how these factors were interconnected at the start of the academic year and how they were longitudinally associated later in the academic year. Survey data were collected among students at a Dutch university of applied sciences in November 2023 (T1; N = 497) and June 2024 (T2; n = 207). Data were collected on mental wellbeing, academic stressors, academic self-perceptions, coping styles and social environmental factors. A Gaussian Graphical Model was used to estimate the cross-sectional network at T1, and longitudinal associations from T1 to T2 were examined using regularized regression (LASSO). The findings showed that associations in the cross-sectional network were generally modest. Connections were mainly observed between conceptually related variables, including academic stressors, coping styles, and social environmental factors. Mental wellbeing showed few direct associations with the other constructs in the network, but both mental wellbeing and social support showed relatively high centrality, indicating that they were strongly connected within the overall network structure. Longitudinal analyses indicated substantial stability across the academic year, as most variables were primarily related to their own prior levels and only a limited number of associations between different variables were observed over time. These findings suggest that student mental wellbeing was embedded in a relatively stable system of related experiences. They also illustrate that cross-sectional variable network approaches may have limitations when conditional associations are weak and constructs overlap conceptually, particularly when used to draw conclusions about complex socio-ecological processes.

This article reports an effectiveness study of Neighbourhood Active & Connected, a novel neighbourhood-oriented approach to promote healthy ageing among older adults from lower socioeconomic positions (LSPs). This group faces significant health disparities and limited access to preventive care. The intervention aims to enhance physical activity, reduce loneliness, and improve social cohesion and health-related quality of life, while fostering digital engagement to support healthcare access and independence. To evaluate its impact, we conducted a parallel, superiority, 1:1 cluster-randomised controlled trial, randomly assigning LSP neighbourhoods and their inhabitants to either the intervention (N=560) or a waitlist control group (N=369), with 277 and 221 participants completing the baseline assessment, respectively. The intervention resulted in increases in physical activity after three months, with improvements in both moderate-to-vigorous (B=346.618 min/week, SE=141.185, p=0.014) and light-intensity (B=583.612 min/week, SE=180.736, p=0.001), although these effects diminished by six months. Loneliness, however, showed sustained reductions after three (B=-0.436, SE=0.229, p=0.058) and six months (B=-0.765, SE=0.237, p<0.001), highlighting the potential of a neighbourhood-oriented approach to reducing social isolation. No significant improvements were found in health-related quality of life, social cohesion, or digital engagement. These findings suggest that while neighbourhood-oriented interventions may effectively improve physical activity and reduce loneliness, further research and more targeted strategies are needed to enhance lasting improvements in physical activity and address broader health and well-being outcomes. This study emphasises the importance of considering the socio-environmental context in interventions and the need for ongoing support to maintain behavioural changes among older adults from lower socioeconomic backgrounds.

In questionnaire development, content validity is usually operationalized by using items that comprehensively express all aspects of the object of measurement. We argue that this often leads to content coverage that is too broad, and that content validity needs pruning down when the intention is to measure conditions or constructs that should be discerned from other conditions or constructs – which is almost always the case. This pruned-down version of content validity we name “cue validity”, signifying the uniqueness of indicators for a construct. We show what negative consequences have been of ignoring cue validity in previously developed questionnaires and illustrate how taking cue validity into account can guide the validation of new questionnaires.

Although emotion regulation within romantic couples is considered an important causal factor in keeping the relationship healthy, this topic has not been extensively researched. In this study we investigated the perception and expression of attachment-related emotional needs and the responsiveness of partners to each other’s emotional needs as central elements of emotion regulation in romantic couples. An intensive longitudinal research design with high-frequent measurements was used to study these dynamic processes in romantic relationships. Clinical couples (N = 16) reporting clinically relevant relationship difficulties after cancer treatment were compared with healthy couples (N = 12). At ten times per day during seven consecutive days both partners completed a brief questionnaire about their stress perception, attachment-related emotional needs, and perceived partner responsiveness. When both variables were measured simultaneously, expressed emotional needs were positively related to partners’ responsiveness in the full sample, although more so in clinical couples than in healthy couples. However, greater expressed emotional needs predicted greater partner responsiveness at the next measurement point only in clinical couples, whereas this effect was absent in healthy couples. Furthermore, higher expressed emotional needs predicted lower partner responsiveness in participants with higher level of anxious attachment orientation, whereas this association was absent at mean and low levels. The findings in this study supported several predictions based on the theoretical premises. The unexpected moderation effects of clinical status (clinical vs. healthy couples) on the association of expressed emotional needs and perceived partner responsiveness are discussed.

This study explored the role of sexual excitation and inhibition and attachment orientation in sexual desire and arousal. We investigated whether attachment orientation moderated the associations between sexual excitation and inhibition and sexual desire and arousal. A convenience sample of 358 participants (242 women and 116 men; mean age: 37.6, SD: 12.0) completed online questionnaires including the Sexual Inhibition/Sexual Excitation Scales–Short Form, the Experiences in Close Relationships scale, the Female Sexual Function Index (women only), and the International Index of Erectile Function (men only). Associations were tested using multiple linear regression analysis. Sexual excitation/inhibition and attachment anxiety independently predicted part of the variance in sexual desire and arousal. Relationship duration negatively predicted level of sexual desire, while male gender positively predicted level of sexual arousal. The associations between sexual excitation/inhibition and sexual desire and arousal were not moderated by attachment orientation. Further research into the interaction of sexual excitation and sexual inhibition proneness and adult attachment orientation as determinants of sexual desire and arousal seems warranted.

Substance use disorders (SUDs) are a significant concern for public health. Preliminary research suggests that physical activity (PA) may offer health benefits for individuals in SUD treatment. However, conclusive evidence is still lacking. High relapse rates, the presence of considerable comorbidity, and issues with motivation among people with SUDs are common barriers for PA maintenance in interventions at residential SUD treatment facilities. Our non-concurrent multiple-baseline N-of-1 study will investigate the effects and feasibility of a motivational intervention designed to increase PA motivation and PA maintenance in n = 6 residents with SUDs in a Western Australian treatment facility. The study will consist of a baseline (6 weeks), an intervention (10 weeks), and a maintenance (12 weeks) period. Participants will receive a motivational intervention consisting of 10 weekly intervention and two booster sessions. Ecological momentary assessments will be used to collect daily data on PA motivation, craving for substance use, and affect. Trajectories of all variables across participants and study phases will be plotted and non-overlap methods and randomisation tests will be employed to assess changes between study phases. Linear trends will be modelled, and non-linear trends will be explored using a piecewise regression model and a generalised logistic approach. The successful implementation of the intervention may be valuable for the development of larger-scale motivation-embellished PA interventions in SUD populations.

Abstract Background Reviews of depression interventions in nursing home residents resulted in positive findings. However, because of the heterogeneity of the studies, it remains unclear what works for whom. Considering moderator effects may contribute to a comprehensive understanding of depression treatment in residents. Therefore, this study aims to review depression interventions, examining moderator effects of (1) residents’ factors, and (2) components specific of interventions. Methods A Bayesian network meta-analysis of randomized controlled trials primarily aimed at reducing depressive symptoms among residents was conducted. First, intervention types, e.g., exercise interventions, were compared to care as usual. Second, meta-regression analyses were conducted for moderator effects of residents’ factors (i.e., severity of depressive symptoms, physical dependency, and cognitive impairment) and components identified as specific to an intervention (e.g., music, creativity, positivity). Results Our search across six databases resulted in 118 eligible studies: 16 on neurobiological interventions, 102 on non-pharmacological interventions. Compared to care as usual, cognitive interventions, such as cognitive behavioral therapy and goal-oriented therapy, showed the strongest effects (MD = -1.00, 95% CrI [-1.40 to -0.66]). Furthermore, the severity of depressive symptoms moderated the effect of interventions (ƅ = -0.63, CrI 95% [-1.04 to -0.22]), while none of fifteen identified intervention-specific components did. In residents with a depression diagnosis, there were larger effect sizes for interventions including daily structure, psychoeducation, healthy food, creativity, positivity, and an activating/encouraging environment, whereas interventions focusing on distraction and relaxation had larger effect sizes in those residents without. Conclusions By examining the moderator effects, we provided an integrative perspective on the observed variations in effects across different target groups, and components of depression interventions. This approach underscores the complex nature of interventions, emphasizing the need for continued transdisciplinary research, and the exploration of potential moderators. Future investigations should carefully assess residents’ factors and choose interventions and their components accordingly.

Cyclical patterns in ecological momentary assessment (EMA) data on emotions have remained relatively underresearched. Addressing such patterns can help to better understand emotion dynamics across time and contexts. However, no general rules of thumb are readily available for psychological researchers to determine the required sample size for measuring cyclical patterns in emotions. This study, therefore, estimates the minimum required sample sizes—in terms of the number of measurements per time period and subjects—to obtain a power of 80% given a certain underlying cyclical pattern based on input parameter values derived from an empirical EMA dataset. Estimated minimum required sample sizes varied between 50 subjects and 10 measurements per subject for accurately detecting cyclical patterns with a large magnitude, to 60 subjects and 30 measurements per subject for cyclical patterns of small magnitude. The resulting rules of thumb for sample sizes are discussed with a number of considerations in mind.

Background Problematic Hypersexuality (PH) is defined as a distress caused by hypersexuality, to the extent that seeking treatment is considered. PH was previously measured with instruments stemming from different perspectives on problems related to hypersexuality. These instruments might best be analyzed in unison to discover the most optimal set of characteristics to measure PH. Methods A total of 58 items were investigated with Item Response Theory (IRT). We included 1211 participants (592 women, 618 men, 1 other) from a representative Dutch general population sample of 18 years or older. In addition, 371 participants (116 women, 253 men, 2 other) in a web-based survey who sought information on their current level of PH were included. This latter group was divided into those that did or did not consider treatment and group differences in item averages were assessed. Results After item selection, 26 out of 58 items were retained and divided in two scales: Emotion Dysregulation-PH – 9 items representing the distressing emotional patterns coinciding with hypersexual preoccupation – and Negative Effects-PH – 17 items representing the negative consequences of patterns of hypersexual thoughts and behavior. Assumptions for IRT analyses were met (unidimensionality, local independence and monotonicity). After an IRT graded response model was fit, the scales showed sufficient reliability for the target population of hypersexual individuals. In the general population the scales showed large floor effects and were less reliable. Conclusions With this study a first step is taken in validating two complementary item banks to measure PH. Further development of the item banks should include the investigation of responsiveness. New items should be constructed to assess less-explored areas of PH and improve differentiating power of the scales. This study showed that diagnostic accuracy for PH is currently difficult to attain with a survey, even when using an extended item set representing the most unique characteristics of PH.

IntroductionThe aim of the present study was to evaluate the effects of an individual music therapy intervention and an individual music listening intervention on neuropsychiatric symptoms and quality of life in people with dementia living in a nursing home and on professional caregiver’s burden to be able to make statements about their specific value of application in clinical practice.MethodsA multicenter single blind randomized controlled trial with three groups was performed: an individual music therapy intervention (IMTI) group (n = 49), an individual music listening intervention (IMLI) group (n = 56) and a control group (n = 53) receiving usual care. The interventions were given during three weeks, three times a week on non-consecutive days during 30–45 minutes for in total nine sessions. The endpoint of the study is the difference from baseline to interim (1,5 week), post-intervention (3 weeks) and follow-up (6 weeks) in reported scores of problem behaviour (NPI-NH) and quality of life (Qualidem) in people with dementia and occupational disruptiveness (NPI-NH) in care professionals.ResultsIn total 158 people with dementia were randomized to one of the two intervention groups or the control group. Multilevel analyses demonstrated that hyperactive behaviour assessed by the NPI-NH was significantly more reduced for the IMLI group at follow up and that restless behaviour assessed by the Qualidem was significantly more reduced for the IMTI group at post and follow-up measurement compared to the control group. No significant effects between groups were found in other NPI-NH clusters or Qualidem subscales.ConclusionIn conclusion, because we found no convincing evidence that the IMTI or IMLI is more effective than the other both interventions should be considered in clinical practice. For the future, we advise further research into the sustainability of the effects with alternative designs, like a single case experimental design.

BackgroundThis study focuses on the Budd app, a mobile health intervention designed for gay, bisexual, and other men who have sex with men who participate in chemsex. Chemsex, the use of psychoactive drugs in a sexual context, presents substantial health risks including increased HIV transmission and mental health issues. Addressing these risks requires innovative interventions tailored to the unique needs of this population. ObjectiveThis study aims to evaluate the effectiveness of the Budd app in promoting drug harm reduction practices among its users, focusing on knowledge, behavioral intention, risk behavior awareness, and self-efficacy. MethodsThe study used a mixed methods approach, combining a single-case experimental design and a pre-post study. A total of 10 participants from an outpatient clinic were recruited, and each attended the clinic 3 times. During the first visit, participants installed a restricted version of the Budd app, which allowed them to report daily mood and risk behavior after chemsex sessions. Phase A (baseline) lasted at least 2 weeks depending on chemsex participation. In the second visit, participants gained full access to the Budd app, initiating phase B (intervention). Phase B lasted at least 6 weeks, depending on chemsex participation, with identical data input as phase A. Participants completed pre- and postintervention surveys assessing behavioral determinants during the first and third visit. ResultsThe study observed an increased knowledge about chemsex substances postintervention, with a mean percentage improvement in knowledge scores of 20.59% (SD 13.3%) among participants. Behavioral intention and self-efficacy showed mixed results, with some participants improving while others experienced a decrease. There was also a variable impact on awareness of risk behavior, with half of the participants reporting a decrease postintervention. Despite these mixed results, the app was generally well-received, with participants engaging with the app’s features an average of 50 times during the study. ConclusionsThe Budd app showed effectiveness in enhancing knowledge about chemsex substances among gay, bisexual, and other men who have sex with men. However, its impact on safe dosing behavior, behavioral intention, self-efficacy, and risk behavior awareness was inconsistent. These findings suggest that while educational interventions can increase knowledge, translating this into behavioral change is more complex and may require more participants, a longer follow-up period, and additional strategies and support mechanisms.

Electronic health (eHealth) and mobile health (mHealth) could stimulate physical activity (PA) in a time-efficient and cost-effective way. This randomized controlled trial aims to investigate effects on moderate-to-vigorous PA (MVPA) of different combined computer- and mobile-based PA interventions targeted at adults aged 50 years and over. Participants (N = 954) were randomly allocated to a basic existing computer-based intervention (Active Plus [AP] or I Move [IM]) supplemented with one of three mobile elements being (1) activity tracker (AT), (2) ecological momentary intervention (EMI), or (3) chatbot (CB) or a control group (CG). MVPA was assessed via the SQUASH at baseline (T0), 3 months (T1), and 6 months (T2) and via accelerometers at T0 and T2. No intervention effects were found on objective (p = .502) and subjective (p = .368) MVPA for main research groups (AP/IM + AT, AP/IM + EMI, AP/IM + CB). Preliminary MVPA findings for subgroups (AP + AT, AP + EMI, AP + CB, IM + AT, IM + EMI, IM + CB) combined with drop-out data showed potential for the computer-based intervention AP with an integrated AT. Based on these preliminary findings, eHealth developers can be recommended to integrate ATs with existing computer-based PA interventions. However, further research is recommended to confirm the findings as a result of the exploratory nature of the subgroup analyses.

Few weight loss and weight loss maintenance interventions are tailored to include factors demonstrated to predict the user's behavior. Establishing the feasibility and acceptability of such interventions is crucial. The aim of this study was to assess the acceptability and feasibility of a theory-based, tailored, online-delivered weight loss and weight loss maintenance intervention (Choosing Health). We conducted a mixed methods process evaluation of the Choosing Health tailored intervention, nested in a randomized controlled trial (N = 288) with an embedded N-of-1 study, investigating participants' and implementers' experiences related to intervention context, implementation, and mechanisms of impact. Measures included: (i) surveys, (ii) data-prompted interviews (DPIs) with study participants, (iii) semi-structured interviews with implementers, and (iv) intervention access and engagement data. Five themes described the acceptability of the intervention to participants: (i) monitoring behavior change and personal progress to better understand the weight management process, (ii) working collaboratively with the intervention implementers to achieve participants' goals, (iii) perceived benefits of non-judgmental and problem-solving tone of the intervention, (iv) changes in personal perception of the weight management process due to intervention tailoring, and (v) insufficient intervention content tailoring. The intervention delivery was feasible, however, emails and text messages differed in terms of accessibility and resources required to deliver the content. The use of Ecological Momentary Assessment as a technique to gather personal data for further tailoring was acceptable, and facilitated behavior change monitoring. Personalization of the intervention content above and beyond domain-specific issues, for example, by addressing participants' social roles may better match their needs. Support from the implementers and feedback on body composition changes may increase participants' engagement.
