The impact of greenery on physical activity and mental health of adolescent and adult residents of deprived neighborhoods: A longitudinal study.

The aim of the study is to assess the impact of perceived and objective changes in greenery on physical activity and mental health of adolescents and adults living in severely deprived neighborhoods in the Netherlands. Longitudinal data regarding changes in greenery, walking, cycling, and depressive symptoms (CES-D), were gathered for 401 adolescents and 454 adults, using questionnaires and interviews with local district managers. Multivariate linear regression models examined the association between greenery and outcome variables, correcting for demographic and socioeconomic covariates and season. Overall, the results showed small and non-significant associations, with two exceptions. Objective improvements in greenery were associated with smaller decline in adolescents' leisure time cycling, and improvements in perceived greenery were related to a decrease in adults' depressive symptoms. In addition, there were several subgroup effects. In conclusion, changes in greenery did not yield consistent positive results among residents of severely deprived neighborhoods. However, there are some indications regarding positive effects of greenery in certain subgroups.

Defining subgroups of low socioeconomic status women at risk for depressive symptoms: the importance of perceived stress and cumulative risks.

BACKGROUND: Most disadvantaged women are exposed to risk factors for depression, but not all necessarily have an identical risk for this mental health problem. A better prediction of which low socioeconomic status (SES) women are most at risk for depressive symptoms can help target preventive interventions at high-risk subgroups most in need of support. AIMS: Exploring which demographic, socioeconomic and psychological risk factors are associated with self-reported depressive symptoms in a sample of low-SES women and whether the number of risk factors might expose them to an accumulated risk. METHODS: Between April 2005 and November 2007, 519 disadvantaged women from urban neighbourhoods in Maastricht, a southern Dutch city, participated in a cross-sectional survey on stress and depressive symptoms. RESULTS: Lower education levels, no current employment and lower net monthly family incomes were socioeconomic risk factors associated with higher scores for depressive symptoms. The psychological risk factor 'perceived stress' had the highest explained variance and was most strongly associated with depressive symptoms. Women exposed to multiple risk factors across domains had a cumulated risk for depressive symptomatology. CONCLUSION: Low-SES women who seem most eligible for targeted preventive action are those with cumulative risks. Depression prevention strategies for this population may benefit from focusing on perceived stress since this is an important modifiable risk factor.

Design of a quasi-experiment on the effectiveness and cost-effectiveness of using the child-interview intervention during the investigation following a report of child abuse and/or neglect.

BACKGROUND: In the Netherlands, suspected cases of child maltreatment can be reported to an advice and reporting center on child abuse and neglect (Advies- en Meldpunt Kindermishandeling or AMK). AMKs investigate these reports, screen for problems in the family and its surroundings and refer to child welfare. Over the last decades the focus of AMK investigations has changed from an adult-only approach to a more child-oriented approach using a Child-Interview intervention. The effects and cost-effectiveness of AMK involvement in the Netherlands have never been studied. The primary aim of this study is therefore to examine the effect of the participation of maltreated children aged 6-18 years in the Child-Interview intervention on their mental health and quality of life. As a second aim, this study will examine the balance between additional costs and effects of the Child-Interview intervention in comparison with AMK investigation without the Child-Interview intervention (adult-only intervention). DESIGN/METHODS: A quasi-experiment will be performed consisting of two post-intervention measurements of two nonequivalent groups: an intervention group, in which the Child-Interview intervention has been used during the AMK investigation, and a control group, in which the intervention has not been used (adult-only intervention). Participants from an ongoing prospective study on the mental health and quality of life of maltreated children after a report to an AMK, will be contacted to complete a questionnaire twice. Multivariate regression analyses will be used to determine effectiveness of the Child-Interview intervention. The economic evaluation will involve a cost-effectiveness analysis and a cost-utility analysis. RESULTS/DISCUSSION: This will be the first study to examine the effect of AMK involvement in the Netherlands. Using the Child-Interview intervention during AMK investigation may prevent or reduce negative outcomes of child maltreatment, which may result in a lower consumption of healthcare and other services. In addition, the importance of economic evaluations is increasingly recognized, and economic evaluations about child maltreatment are scarce. Limitations include the risk of potential recall bias and selection bias. TRIAL REGISTRATION: NTR3728, funded by ZonMw, project 15700.2012.

What moves them? Active transport among inhabitants of Dutch deprived districts.

BACKGROUND: Active modes of transport like walking and cycling have been shown to be valuable contributions to daily physical activity. The current study investigates associations between personal and neighbourhood environmental characteristics and active transport among inhabitants of Dutch deprived districts. METHOD: Questionnaires about health, neighbourhoods, and physical activity behaviour were completed by 742 adults. Data was analysed by means of multivariate linear regression analyses. RESULTS: Being younger, female, and migrant and having a normal weight were associated with more walking for active transport. Being younger, male, and native Dutch and having a normal weight were associated with more cycling for active transport. Neighbourhood characteristics were generally not correlated with active transport. Stratified analyses, based on significant person-environment interactions, showed that migrants and women walked more when cars did not exceed maximum speed in nearby streets and that younger people walked more when speed of traffic in nearby streets was perceived as low. Among migrants, more cycling was associated with the perceived attractiveness of the neighbourhood surroundings. DISCUSSION AND CONCLUSION: Results indicated that among inhabitants of Dutch deprived districts, personal characteristics were associated with active transport, whereas neighbourhood environmental characteristics were generally not associated with active transport. Nevertheless, interaction effects showed differences among subgroups that should be considered in intervention development.

Design of a prospective study on mental health and quality of life of maltreated children (aged 5-16 years) after a report to an advice and reporting center on child abuse and neglect.

BACKGROUND: Child maltreatment is recognized as a widespread problem with huge implications for mental health and quality of life. Studies have repeatedly shown that victims of child maltreatment report significantly more adverse life outcomes than non-victims. The main objective of the study is (1) to examine the mental health and quality of life of maltreated children over a 1.5 year period beginning shortly after a report has been filed with an Advies- en Meldpunt Kindermishandeling (AMK) (advice and reporting center on child abuse and neglect). Secondary objectives are: (2) to examine how relevant determinants influence the mental health and quality of life of maltreated children, and (3) to examine differences in mental health and quality of life outcomes when comparing families of Dutch origin with families originating from Morocco and Suriname. METHODS/DESIGN: A prospective study will be performed, in which parent-child dyads will be followed over a 1.5 year period. Participants will be recruited shortly after the report to the AMK and they will be asked to complete a questionnaire four times, at baseline and every six months thereafter. Data will be analyzed using a longitudinal multi-level analysis. DISCUSSION: The study is expected to yield evidence about the mental health and quality of life of maltreated children and about determinants that influence their mental health and quality of life outcomes. Strengths of this study are (1) the design which makes it possible to start examining outcomes shortly after or even during the actual maltreatment and to follow parent-child dyads for 1.5 years, and (2) asking children as informants about their own situation by making use of self-report questionnaires as much as possible. Limitations include the risks of selection bias and loss to follow-up during 1.5 years of data collection. TRIAL REGISTRATION: NTR3674, funded by ZonMw, project 15700.2012.

A randomized controlled trial of combined exercise and psycho-education for low-SES women: short- and long-term outcomes in the reduction of stress and depressive symptoms.

Exercise may have both a preventive and a therapeutic impact on mental health problems. The Exercise without Worries intervention aims to reduce stress and depressive symptoms in low-SES women by means of a group-based program combining physical exercise and psycho-education. Between September 2005 and May 2008, 161 Dutch low-SES women with elevated stress or depressive symptom levels were randomly assigned to the combined exercise/psycho-education intervention (EP), exercise only (E) or a waiting list control condition (WLC). The E condition provided low to moderate intensity stretching, strength, flexibility, and body focused training as well as relaxation, while the EP program integrated the exercise with cognitive-behavioral techniques. Depressive symptoms (CES-D) and perceived stress (PSS) were measured before and immediately after the intervention and at 2, 6 and 12 month follow-up. Multilevel linear mixed-effects models revealed no differential patterns in reduction of CES-D or PSS scores between the EP, E and WLC groups on the short (post-test and 2 month follow-up) or long term (6 and 12 months follow-up). Depressive symptom outcomes were moderated by initial depressive symptom scores: women from the EP and E groups with fewer initial symptoms benefited from participation on the short term. Further, women in the EP and E groups with the lowest educational level reported more stress reduction at post-test than women with higher educational levels. In the overall target population of low-SES women, no indications were found that the Exercise without Worries course reduced depressive symptom and stress levels on the short or long term. The findings do suggest, however, that exercise alone or in combination with psycho-education may be a viable prevention option for certain groups of disadvantaged women. Especially those low-SES women with less severe initial problems or those with low educational attainment should be targeted for future depression prevention practice.

Early school outcomes for children of postpartum depressed mothers: comparison with a community sample.

Previous studies of the long-term effects of maternal postpartum depression (PPD) on child development have mostly focused on a limited set of outcomes, and have often not controlled for risk factors associated with maternal depression. The present study compared children of postpartum depressed mothers (n = 29) with children from a community sample (n = 113) in terms of a broad range of developmental outcomes in the early school period. Controlling for risk factors associated with maternal depression, we found that children of postpartum depressed mothers had lower ego-resiliency, lower peer social competence, and lower school adjustment than the community sample children. In addition, girls of postpartum depressed mothers showed lower verbal intelligence, and, unexpectedly, showed fewer externalizing problems than their counterparts in the community sample. Results show that children's capacities to deal with stress and interact with peers in the early school period may be particularly affected by their mothers' PPD.

Psychosocial preventive interventions to reduce depressive symptoms in low-SES women at risk: a meta-analysis.

BACKGROUND: Women who have low socioeconomic status (SES) or live in disadvantaged circumstances are a vulnerable group at risk for depression. Little is known about the efficacy of preventive interventions to reduce depressive symptoms in low-SES women. The aim of this study is to provide an overview of controlled outcome studies and to investigate the overall efficacy and moderators of interventions targeted at reducing depressive symptoms in this population. METHODS: A systematic review and meta-analysis were conducted for 14 studies (N = 1396). The effect size of the studies was computed for outcomes assessing changes in depressive symptom levels using the standardized mean difference effect size. Study, target population, and intervention descriptors expected to influence effect size were analyzed using univariate subgroup and metaregression techniques with mixed-effects statistical models. RESULTS: The estimated overall effect size of 0.31 was significant; study sample characteristics, intervention characteristics and the research design of the studies did not moderate intervention effects. LIMITATIONS: Limitations to this study are the relatively limited number of well controlled studies that could be included in the analyses. CONCLUSIONS: A number of promising programs have been developed specifically for low-SES women, a population at high risk for developing major depression. On average these programs were found to reduce the level of depressive symptoms, with more than half of the studies showing medium to large effect sizes. This indicates that considerable mental health benefits can be gained among disadvantaged women.

Which preventive interventions effectively enhance depressed mothers' sensitivity? A meta-analysis.

Improving depressed mothers' sensitivity is assumed to be a key element in preventing adverse outcomes for children of such mothers. This meta-analysis examines the short-term effectiveness of preventive interventions in terms of enhancing depressed mothers' sensitivity toward their child and investigates what type of intervention is most effective. Thirteen interventions, reported in 10 controlled outcome studies, met the inclusion criteria (N = 918). Meta-analytic results showed a small to medium, significant mean effect size (g = 0.32) with large variation in individual effect sizes (-0.56-1.76). Interventions including baby massage were highly effective in improving maternal sensitivity (g = 0.85). In contrast, individual therapy for the mother proved ineffective in terms of improving maternal sensitivity (g = -0.00). Two other significant predictors of greater effect sizes were the inclusion of a support group and the use of a higher number of intervention methods; however, the significance of these results was largely accounted for by one single study. Our meta-analysis confirms that depressed mothers' sensitivity can be improved by preventive intervention and suggests that baby massage may be an effective intervention method to evoke short-term changes in maternal sensitivity. It is unclear whether these changes are maintained over time.

Exploring recruitment, willingness to participate, and retention of low-SES women in stress and depression prevention.

BACKGROUND: Recruitment, willingness to participate, and retention in interventions are indispensable for successful prevention. This study investigated the effectiveness of different strategies for recruiting and retaining low-SES women in depression prevention, and explored which sociodemographic characteristics and risk status factors within this specific target group are associated with successful recruitment and retention. METHODS: The process of recruitment, willingness to participate, and retention was structurally mapped and explored. Differences between women who dropped out and those who adhered to the subsequent stages of the recruitment and retention process were investigated. The potential of several referral strategies was also studied, with specific attention paid to the use of GP databases. RESULTS: As part of the recruitment process, 12.1% of the target population completed a telephone screening. The most successful referral strategy was the use of patient databases from GPs working in disadvantaged neighborhoods. Older age and more severe complaints were particularly associated with greater willingness to participate and with retention. CONCLUSIONS: Low-SES women can be recruited and retained in public health interventions through tailored strategies. The integration of mental health screening within primary care might help to embed preventive interventions in low-SES communities.

Long-term effects of a home-visiting intervention for depressed mothers and their infants.

BACKGROUND: Whereas preventive interventions for depressed mothers and their infants have yielded positive short-term outcomes, few studies have examined their long-term effectiveness. The present follow-up of a randomised controlled trial (RCT) is one of the first to examine the longer-term effects of an intervention for mothers with postpartum depression and their infants at school-age. In early infancy, the intervention was found effective in improving mother-infant interaction and the child's attachment to its mother. METHODS: Twenty-nine mother-child pairs who completed the intervention are compared with 29 untreated mother-child dyads as to the quality of maternal interactive behaviour and the child outcomes of attachment security to the mother, self-esteem, ego-resiliency, verbal intelligence, prosocial behaviour, school adjustment, and behaviour problems at age 5 (M=68 months). RESULTS: In the total sample no lasting treatment benefits were found, but in families reporting a higher number of stressful life events, children in the intervention group had fewer externalising behaviour problems as rated by their mothers than children in the control group. CONCLUSIONS: In the context of multiple stressful life events the intervention served as a buffer by preventing the development of externalising problems in the child. The results warrant cautious interpretation because of the relatively small sample size and differential attrition revealing the mothers that completed the follow-up assessment to have improved less on maternal sensitivity following the intervention than the mothers who did not participate in the follow-up.

A randomized controlled trial of a home-visiting intervention aimed at preventing relationship problems in depressed mothers and their infants.

This study examined the effect of a mother-baby intervention on the quality of mother-child interaction, infant-mother attachment security, and infant socioemotional functioning in a group of depressed mothers with infants aged 1-12 months. A randomized controlled trial compared an experimental group (n = 35) receiving the intervention (8-10 home visits) with a control group (n = 36) receiving parenting support by telephone. There were assessments pre, post, and follow-up after 6 months. The intervention had positive effects on the quality of mother-infant interaction. Infants in the experimental group had higher scores for attachment security and for one aspect of socioemotional functioning, namely, competence. The intervention proved successful in preventing deterioration of the quality of mother-child interaction.

Correlates of depressed mothers' sensitivity toward their infants: the role of maternal, child, and contextual characteristics.

OBJECTIVE: To examine various maternal, child, and contextual characteristics, as well as the number of risk factors present, to distinguish which factors explain variance in the sensitivity of depressed mothers toward their infants. METHOD: Participants were depressed mothers (n = 84) with their infants ages 1 month up to 1 year. Mothers were videotaped while bathing their children. The recordings were rated using the sensitivity scale of the Emotional Availability Scales. RESULTS: Three characteristics independently contributed to the explained variance in maternal sensitivity: level of education, feelings of parental incompetence, and family income. In addition, two subgroups were found to be particularly at risk: young mothers with high levels of depressive symptoms and low-income mothers who felt insecure about their parental competence. Together, these factors explained 23% of the variation in sensitivity in our sample of depressed mothers. The number of risk factors explained 9.8% of the variation in sensitivity. CONCLUSIONS: The present results have implications for preventive interventions. Identifying specific groups at risk for low maternal sensitivity at an early stage may lead to favorable outcomes of targeted interventions that focus on enhancing depressed mothers' maternal sensitivity and feelings of parental competence.

Bystanding an abused child: testing the applicability of the stages of change construct.

A minority of child abuse cases is recognized by professionals, making the role of non-professional bystanders essential. The stages of change construct, as proposed by the Transtheoretical Model, may provide a useful approach to explain non-professional helping behavior. The objective of this study was to test the applicability of the stages of change construct by (i) assessing whether cognitive determinants distinguish between the stages, (ii) testing the predictive value of the stages for future helping behavior and (iii) examining the mediating role of the stages in the relation between previous and future helping behavior. Data of 126 adult non-professional bystanders were analyzed. Respondents were questioned by telephone or via an Internet questionnaire, at baseline and after a follow-up of about two months later. Attitude toward helping was significantly less positive in pre-contemplation than in the other stages, and self-efficacy expectations were significantly higher in preparation compared with the other stages. Moreover, baseline preparators were more likely to conduct future helping behavior than those in the two earlier stages. Finally, the stages of change mediated the relation between previous and future helping behavior. Initial support was found for the applicability of the stages of change construct for helping behavior by non-professional bystanders.

Social and family correlates of eating problems and muscle preoccupation in young adolescents.

This study examined the unique contribution of a number of social and familial factors to body change strategies and eating problems in youths. A sample of non-clinical adolescents aged 10 to 16 years (N=405) completed a modified version of the Children's Eating Attitudes Test (ChEAT) and questionnaires for measuring various social and familial factors that may play a role in the etiology of eating problems and muscle preoccupation. Regression analyses indicated that specific eating disorder-related factors (such as the encouragement of peers and parents to lose weight or to become more muscular) and more general factors (such as negative parental rearing behaviors and insecure attachment) made independent contributions to problem eating and muscle preoccupation in youths.

One measure, two motives. Prediction of condom use and interaction between two prevention goals among heterosexual young adults: preventing pregnancy and/or sexually transmitted diseases.

Although the dual function of condom use (preventing pregnancy and preventing STDs) is well known, little is known about the determinants of condom use for STD prevention when contraception is not an issue. We compared two intentions to use condoms with a new sex partner: one based on a vignette not mentioning pregnancy risk and one on a vignette explicitly stating there was no risk of pregnancy. We also investigated whether intentions to use condoms change when there is no pregnancy risk, to allow such changes to be predicted from an STD risk-perception perspective. This cross-sectional survey was completed by 151 undergraduate students. The correlation coefficient between the two intentions about condom use approached zero (0.02; p=.783). Logistic regression showed that two STD risk-perception variables distinguished between consistent and non-consistent reporters of their intention to use condoms. Findings are discussed from the perspectives of policy, methodology and theory.
