The objective of this meta-analysis was to determine the longitudinal positive effect of religion or spirituality (R/S) on mental health. We summarized 48 longitudinal studies (59 independent samples) using a random effects model. Mental health was operationalized as a continuous and a dichotomous distress measure, life satisfaction, well-being, and quality of life. R/S included participation in public and private religious activities, support from church members, importance of religion, intrinsic religiousness, positive religious coping, meaningfulness, and composite measures. The meta-analysis yielded a significant, but small overall effect size of r = .08 (95% CI: 0.06 to 0.10). Of eight R/S predictors that were distinguished, only participation in public religious activities and importance of religion were significantly related to mental health (r = .08 and r = .09, respectively; 95% CI: 0.04 to 0.11 and 0.05 to 0.12, respectively). In conclusion, there is evidence for a positive effect of R/S on mental health, but this effect is small.

In the current study, we investigated the psychometric properties of a Dutch translation of the posttraumatic growth inventory in a heterogeneous group of cancer patients. Its original five-factor structure was maintained. The internal consistency of the total scale, as well as its subdimensions, was satisfactory. As expected, the experience of posttraumatic growth was positively related to: emotional expression about the illness, openness to experience, and feelings of innerness. Furthermore, the scale appeared to be sensitive for the demographics age and gender. The experience of posttraumatic growth was not related to negative feelings such as avoidance, anxiety, depression, and neuroticism. Our Dutch translation of the instrument appeared to be a sound measure for the experience of posttraumatic growth in cancer patients.

Insecurely attached patients trusted their physician less than securely attached patients, and in turn were less satisfied with their physician. Their higher levels of general distress were not related to their lower levels of trust. Attachment theory provides a framework to interpret differences in patients' trust, satisfaction and distress, and may help physicians respond in such a way that their patients feel secure, which in turn is expected to result in better health outcomes.

We investigated the psychometric properties of a Dutch translation of the Personal Meaning Profile in a heterogeneous group of cancer patients. Our study resulted in a relatively short scale consisting of 39 of the 57 original items, divided into 5 factors, labeled 'relation with God'; 'dedication to life'; 'fairness of life'; 'goal-orientedness' and 'relations with other people', which can be summed to a total score of the experience of meaning in life. The internal consistency of the total scale as well as of its sub dimensions was high. The experience of meaning in life was positively related to feelings of psychological well-being and negatively to feelings of distress. Furthermore, the experience of meaning in life was also related to trait-like characteristics as personality. Future research can investigate its appropriateness for other populations than cancer patients, and if and how the experience of meaning in life eventually changes as a result of existential threats.
