Socioeconomic inequalities in a 16-year longitudinal measurement of successful ageing.

Background: This study examines to what extent education, occupation and income are associated with the multidimensional process of successful ageing, encompassing trajectories of physical, mental and social functioning in old age.

Methods: We employed 16-year longitudinal data from 2095 participants aged 55-85 years at baseline in the Dutch, nationally representative Longitudinal Aging Study Amsterdam. For 9 indicators of successful ageing, separate Latent Class Growth models were used to identify subgroups of older adults with a 'successful' trajectory.

The Effectiveness of Aftercare for Juvenile and Young Adult Offenders.

This study examined the New Perspectives Aftercare Program (NPAP) for serious juvenile and young adult offenders in The Netherlands. Participants (n = 127) were randomly assigned to NPAP (n = 66) or existing aftercare services ("treatment as usual" [TAU], n = 61). The aim was to determine whether NPAP was effective in decreasing cognitive distortions and criminal thinking patterns and increasing prosocial skills of the juveniles compared with TAU.

Reconviction rates after suspended sentences: comparison of the effects of different types of suspended sentences on reconviction in the Netherlands.

Previous research has focused mainly on determining the effectiveness of suspended sentences compared with other sentences, and seldom on understanding to what extent the different types of suspended sentences reduce recidivism rates. This study examined reconviction rates of offenders (N = 1,258) who received fully or partly suspended prison sentences, with or without special conditions, in 2006 in two of the largest court districts in the Netherlands. Cox proportional hazard models revealed no difference in reconviction rates between fully and partly suspended prison sentences, with and without special conditions.

Anticipated emotions and effort allocation in weight goal striving.

Objective: This study aimed to investigate the influence of anticipated emotions on preventive health behaviour if specified at the level of behavioural outcomes. Consistent with predictions from a recently developed model of goal pursuit, we hypothesized that the impact of emotions on effort levels depended on the perceived proximity to the goal.

Design: Participants with weight-loss intentions were randomly selected from an Internet panel and completed questionnaires at three points in time, baseline (T1; N= 725), 2 weeks later at T2 (N= 582) and again 2 months later at T3 (N= 528).
