The effectiveness of a mobile intervention to reduce young adults' alcohol consumption to not exceed low-risk drinking guidelines.

Background: Young adults' drinking habits often exceed low-risk drinking guidelines. As young adults show increased access, use, and interest in personalized content related to physical and mental well-being, mobile applications might be a suitable tool to reach this target group. This study investigates the effectiveness of "Boozebuster", a self-guided mobile application incorporating various therapeutic principles to reduce young adults' alcohol consumption to not exceeding low-risk drinking guideline levels, compared to an educational website condition. Method: Young adults aged 18-30 wanting to reduce their alcohol consumption entered a two-arm, parallel-group RCT. There were no minimum drinking severity inclusion criteria. Primary outcomes included alcohol consumption quantity and frequency. Secondary outcomes included binge drinking frequency and alcohol-related problem severity. Baseline, 6-week postbaseline, and 3-month post-baseline assessments were analyzed using linear mixed model analyses. Sex, treatment adherence, experienced engagement and motivation to change alcohol use behavior were investigated as moderators. Sub-group analyses contained problem drinkers and binge drinkers. Results: 503 participants were randomized to the intervention or control condition. Results showed no intervention effects on primary or secondary outcomes compared to the control group. Both groups showed within-group reductions on all outcomes. Sub-group analyses in problem drinkers or binge drinkers showed similar results. Motivation to change drinking behavior and experienced engagement with the application significantly moderated the intervention effect regarding the quantity or frequency of alcohol consumption, respectively. Exploratory analyses showed that participants who indicated they wanted to change their drinking patterns during the initial PNF/MI module showed a significantly greater reduction in drinking quantity compared to those who indicated not wanting to change their drinking patterns. Conclusion: The intervention group did not show a greater reduction in alcohol-related outcomes compared to the control group, but both groups showed a similar decrease. Potential explanations include similar effectiveness of both condition due to using a minimal active control in participants predominantly in the action stage of motivation to change. Future research should further explore the effectiveness of using mobile application to reduce young adults' drinking behavior to not exceed low-risk drinking guideline levels and identify factors that motivate participants to engage with such an intervention.

Multilevel Social Mechanisms of Post-Disaster Depression.

This exploratory study empirically shows how community social capital is related to post-disaster depression, whereas most disaster mental health research has focused on posttraumatic stress disorder. We tested the validity of earlier found multilevel social and individual mechanisms of posttraumatic stress for symptoms of post-disaster depression. We used data (n = 231) from a community study after a flood in Morpeth (2008), a rural town in northern England. At the salutary community level, our multilevel analyses showed that, in communities with high social capital, individuals employ less individual social support and coping effort, which protects individuals from developing symptoms of depression. Yet, on the 'dark' individual level of our model, we found that perceiving the disaster as less traumatic after a year was related to more feelings of depression in contrast to previous findings for posttraumatic stress. Our explanation of this finding is that, when the appraisal of the disaster as threatening fades into the background, individuals may perceive the full scope of the disaster aftermath and start to feel depressed. We also found that more social support is related to more depression. Although depressed people may attract or receive more social support, this social support can paradoxically become disabling by reinforcing a sense of dependence, thereby undermining self-esteem and leading to feelings of helplessness. Our results imply that to curb post-disaster depression, boosting community level social capital may be an important starting point for building resilience. At the same time, interventionists need to identify risk groups for whom the stressful experience becomes less intrusive and who experience the burden of dependency on an unequal relationship with ones' social inner circle.

The assessment of psychopathology among traumatized refugees: measurement invariance of the Harvard Trauma Questionnaire and the Hopkins Symptom Checklist-25 across five linguistic groups.

Background: Questionnaires are widely used to assess the mental health status of refugees, whereas their construct validity largely remains unexplored. Objective: This study examined the construct validity of two widely-used instruments for the assessment of PTSD symptoms (Harvard Trauma Questionnaire [HTQ]; 16 items) and symptoms of anxiety and depression (Hopkins Symptom Check list-25 [HSCL-25]; 25 items) among Dutch and refugee patients with different linguistic backgrounds. Method: We applied exploratory factor analyses and measurement invariance analyses to test construct validity.Participants (n =1 256) were divided into five linguistic groups defined by language family, including four non-western linguistic groups (Indo-Iranian [n = 262], Niger-Congo [n = 134], Semitic [n = 288], and South Slavic languages [n = 199]) and one western linguistic group (Germanic languages; Dutch [n = 373]). Results: Exploratory factor analysis yielded a 3-factor structure of the HTQ and a 2-factor structure of the HSCL-25. Measurement invariance 20 analyses on the HTQ showed strong measurement invariance across the groups of refugee patients. However, Dutch patients reported milder symptom severity on most items of the HTQ. Measurement invariance analyses on the HSCL-25 (not conducted in Dutch patients) indicated partial strong measurement invariance across refugee patients. Conclusion: We conclude that mental health constructs measured by the HTQ and the HSCL25 25 are to a large extent interpreted in a similar way by refugee patients. This indicates that these instruments can be applied in non-western refugee patient populations, and that local idioms of distress and inherent response patterns may not play a major role when applying the HTQ and the HSCL-25 in these populations. Yet, whereas meaningful comparisons of observed PTSD and depression scores between groups of refugee patients with different non30 western linguistic background are feasible, comparisons between patients with a western and non-western linguistic background, as well as comparisons of anxiety scores, are likely to be biased. Future studies need to establish whether the commonly used cut-off scores of both questionnaires apply for refugee patients with non-western linguistic backgrounds.

In search of links between social capital, mental health and sociotherapy: a longitudinal study in Rwanda.

UNLABELLED: To date, reviews show inconclusive results on the association between social capital and mental health. Evidence that social capital can intentionally be promoted is also scarce. Promotion of social capital may impact post-conflict recovery through both increased social cohesion and better mental health. However, studies on community interventions and social capital have mostly relied on cross-sectional study designs. We present a longitudinal study in Rwanda on the effect on social capital and mental health of sociotherapy, a community-based psychosocial group intervention consisting of fifteen weekly group sessions. We hypothesized that the intervention would impact social capital and, as a result of that, mental health. We used a quasi-experimental study design with measurement points pre- and post-intervention and at eight months follow-up (2007-2008). Considering sex and living situation, we selected 100 adults for our experimental group. We formed a control group of 100 respondents with similar symptom score distribution, age, and sex from a random community sample in the same region. Mental health was assessed by use of the Self Reporting Questionnaire, and social capital through a locally adapted version of the short Adapted Social Capital Assessment Tool. It measures three elements of social capital: cognitive social capital, support, and civic participation. Latent growth models were used to examine whether effects of sociotherapy on mental health and social capital were related. Civic participation increased with 7% in the intervention group versus 2% in controls; mental health improved with 10% versus 5% (both: p < 0.001). Linear changes over time were not significantly correlated. Support and cognitive social capital did not show consistent changes. These findings hint at the possibility to foster social capital and simultaneously impact mental health. Further identification of pathways of influence may contribute to the designing of psychosocial interventions that effectively promote recovery in war-affected populations.

The effect of the postdisaster context on the assessment of individual mental health scores.

Many scholars question the immense variation in rates of mental health outcomes across disaster studies. This study explains this variation by putting forward 2 methodological problems that are inherent to the effect of a disaster context on mental health screening scores. The Hopkins Symptom Checklist-25 was administered in a flood-affected group (n = 318) and a nonaffected group (n = 304) in Uttar Pradesh, India. The affected group showed much higher mean scores on subscales of anxiety and depression. However, factor analyses (i.e., confirmatory factor analyses [CFA] and multilevel confirmatory factor analyses [MCFA]; Muthén, 1994) revealed 2 methodological phenomena that account for the differences in scores. First, the outcomes revealed that a large proportion of covariance between observed mental health variables did not refer to the latent concepts of interest (depression and anxiety), but to the context of both groups (disaster affected vs. nonaffected). The shared effect of the disaster on the context explained a large proportion of the covariances between the items and biased outcomes. Second, after dissecting this group variance, the construct validity of the assessments of anxiety and depression was revealed to be poor and unstable across both groups. The subscales of anxiety and depression referred to different concepts in both groups. These 2 methodological problems have not been discussed thus far, but they contribute to the variation in mental health outcomes across disaster studies.

The impact of recurrent disasters on mental health: a study on seasonal floods in northern India.

INTRODUCTION: Very little is known on the impact of recurrent disasters on mental health. Aim The present study examines the immediate impact of a recurrent flood on mental health and functioning among an affected population in the rural district of Bahraich, Uttar Pradesh, India, compared with a population in the same region that is not affected by floods. METHODS: The study compared 318 affected respondents with 308 individuals who were not affected by floods. Symptoms of anxiety and depression were assessed by the Hopkins Symptom Checklist-25 (HSCL-25). Psychological and physical functioning was assessed by using the Short Form-12 (SF-12). RESULTS: The affected group showed large to very large differences with the comparison group on symptoms of anxiety (D = .92) and depression (D = 1.22). The affected group scored significantly lower on psychological and physical functioning than the comparison group (respectively D = .33 and D = .80). However, hierarchical linear regressions showed no significant relationship between mental health and the domains of functioning in the affected group, whereas mental health and the domains of functioning were significantly related in the comparison group. CONCLUSION: This study found a large negative impact of the recurrent floods on mental health outcomes and psychological and physical functioning. However, in a context with recurrent floods, disaster mental health status is not a relevant predictor of functioning. The findings suggest that the observed mental health status and impaired functioning in this context are also outcomes of another mechanism: Both outcomes are likely to be related to the erosion of the social and environmental and material context. As such, the findings refer to a need to implement psychosocial context-oriented interventions to address the erosion of the context rather than specific mental health interventions.

The mechanisms that associate community social capital with post-disaster mental health: a multilevel model.

Many scholars have advocated that the time has come to provide empirical evidence of the mechanisms that associate community social capital with individual disaster mental health. For this purpose we conducted a study (n = 232) one year after a flood (2008) in Morpeth, a rural town in northern England. We selected posttraumatic stress as an indicator of disaster mental health. Our multilevel model shows that high community social capital is indirectly salutary for individual posttraumatic stress. In particular, in communities (defined as postcode areas) with high structural social capital, the results suggest that individuals confide in the social context (high cognitive social capital) to address disaster-related demands (high collective efficacy), and employ less individual psychosocial resources (i.e. coping strategies and social support). This "conservation of individual psychosocial resources" in a salutary social context decreases the association between the appraisal of the disaster and posttraumatic stress. As a result of this mechanism, individuals suffer less from posttraumatic stress in communities with high social capital. These findings provide new insights how intervention policies aimed at strengthening both objective and subjective dimensions of social capital may reduce post-disaster mental health.

Social capital and post-disaster mental health.

BACKGROUND: Despite national and international policies to develop social capital in disaster-affected communities, empiric evidence on the association between social capital and disaster mental health is limited and ambiguous. OBJECTIVE: The study explores the relationship between social capital and disaster mental health outcomes (PTSD, anxiety, and depression) in combination with individual factors (appraisal, coping behavior, and social support). DESIGN: This is a community-based cross-sectional study in a flood-affected town in northern England. The study is part of the MICRODIS multi-country research project that examines the impact of natural disasters. It included 232 flood-affected respondents. RESULTS: The findings showed that a considerable part of the association between cognitive and structural social capital and mental health is exerted through individual appraisal processes (i.e. property loss, primary and secondary appraisal), social support, and coping behavior. These individual factors were contingent on social capital. After the inclusion of individual characteristics, cognitive social capital was negatively related to lower mental health problems and structural social capital was positively associated to experiencing anxiety but not to PTSD or depression. Depression and anxiety showed a different pattern of association with both components of social capital. CONCLUSIONS: Individual oriented stress reducing interventions that use appraisal processes, social support, and coping as starting points could be more effective by taking into account the subjective experience of the social context in terms of trust and feelings of mutual support and reciprocity in a community. Findings indicate that affected people may especially benefit from a combination of individual stress reducing interventions and psychosocial interventions that foster cognitive social capital.
