“…In nonrandomised trials such as the present study using change scores as dependent variable should be preferred over ANCOVA as the latter tends to deliver biased results (Jamieson, 2004;van Breukelen, 2013). These change scores inform about the extent and direction of change but not about the absolute value in cognition or in behaviour.…”

Handwashing with soap effectively prevents diarrhoea, a leading cause of death in infants. Theory-based interventions are expected to promote handwashing more successfully than standard approaches. The present article investigates the underlying change processes of theory-based handwashing interventions. A nonrandomised field study compared a standard approach to two theory-based interventions that were tailored to the target population, the inhabitants of four villages in southern Ethiopia (N = 408). Data were collected before and after interventions by structured interviews and analysed by mediation analysis. In comparison to the standard approach (i.e., education only), education with public commitment and reminder was slightly more effective in changing social-cognitive factors and handwashing. Education with an infrastructure promotion and reminder was most effective in promoting handwashing through enhancing social-cognitive factors. The results confirm the relevance of testing interventions' underlying change processes.

“…The dysphoria main effect was not significant, F(1, 62) = 0.17, p = .68. As HR baseline values did not significantly correlate with HR reactivity, r(66) = -.11, p = .39, and in light of the quasiexperimental study design (see Jamieson, 2004), we did not adjust HR reactivity with respect to HR baseline values.…”

The present study extends past research about reduced reward responsiveness in depression by assessing effort-related cardiovascular responses during anticipation of a social reward. Dysphoric (i.e., subclinically depressed) and nondysphoric participants worked on a cognitive task. Half the participants in each group expected the possibility to subscribe to a social exchange internet site. Effort mobilization during task performance was assessed by participants' cardiovascular reactivity. Confirming the predictions, nondysphoric participants in the social-reward condition had higher reactivity of pre-ejection period, systolic blood pressure, and heart rate, compared to the other three cells. In contrast, dysphoric participants' cardiovascular reactivity was generally low. These findings indicate that social-reward function is indeed impaired in subclinical depression. Implications for social punishment are discussed.
