A Pilot Study Assessing the Relationship Between Child Harming Thoughts and Postpartum Depression

This pilot study explored relationships between postpartum mood and child harming thoughts. Fifty mothers from an outpatient pediatric office completed the Edinburgh Postnatal Depression Scale (EPDS), Postpartum Depression Predictors Inventory-Revised (PDPI-R), and Beck Anxiety Inventory (BAI). Participants also completed the Child Thoughts Inventory (CTI), a modified version of the Yale-Brown Obsessive-Compulsive Inventory (Y-BOCS) and Florida Obsessive-Compulsive Inventory (FOCI). Results indicated significant positive correlations between postpartum depression and anxiety and frequency and intensity of child harming thoughts. In addition, having a poor self-view was significantly correlated with intensity of child harming thoughts and previous anxiety was correlated with both frequency and intensity of child harming thoughts. Despite the fact that mothers experiencing postpartum mood disturbances rarely harm their infants the findings of this pilot study suggest that these women may have frequent and intense ego-dystonic thoughts about harming their children. Results also suggest that postpartum depression and anxiety may share similar cognitive processes.     

Spontaneously hypertensive, Wistar Kyoto and Sprague-Dawley rats differ in their use of place and response strategies in the water radial arm maze

This study further characterises the use of mnemonic systems in the spontaneously hypertensive rat (SHR), which is frequently used as a rodent model of attention deficit hyperactivity disorder. The objective of this study was to assess the preference of male SHR, Wistar-Kyoto (WKY) and Sprague-Dawley (SD) rats for a place or response strategy when trained on an ambiguous T-maze task, and also to examine whether all strains acquired information about both strategies during ambiguous training, regardless of their preferred strategy. In the first experiment, SHR and WKY showed a preference for a response strategy on the ambiguous T-maze task; in contrast, SD displayed a preference for a place strategy. In the second experiment, all strains demonstrated that they learned information about both the response and place strategies during ambiguous training. However, on a conditioned place preference test SHR did not display as strong a preference for the place arm as WKY and SD. This finding supports previous research in a conditioned cue preference test, in which SHR did not display a preference for the cue associated with the platform. These observations that the strains differ with respect to behavioural strategy in a learning task suggest that they differ in the underlying neural circuitry that serves goal-directed behaviour, and are consistent with SHR having deficits associated with the nucleus accumbens.     

Behavioral, normative and control beliefs underlying low-fat dietary and regular physical activity behaviors for adults diagnosed with type 2 diabetes and/or cardiovascular disease

Promoting healthy lifestyle behaviors is an important aspect of interventions designed to improve the management of chronic diseases such as Type 2 diabetes and cardiovascular disease. The present study used Ajzen's (1991) theory of planned behavior as a framework to examine beliefs amongst adults diagnosed with these conditions who do and do not engage in low-fat dietary and regular physical activity behaviors. Participants (N = 192) completed a questionnaire assessing their behavioral, normative and control beliefs in relation to regular, moderate physical activity and eating foods low in saturated fats. Measures of self-reported behavior were also examined. The findings revealed that, in general, it is the underlying behavioral beliefs that are important determinants for both physical activity and low-fat food consumption with some evidence to suggest that pressure from significant others is an important consideration for low-fat food consumption. Laziness, as a barrier to engaging in physical activity, also emerged as an important factor. To encourage a healthy lifestyle amongst this population, interventions should address the perceived costs associated with behavioral performance and encourage people to maintain healthy behaviors in light of these costs.     

Using Judgmental Anchors to Establish Challenging Self-Set Goals Without Jeopardizing Commitment

We applied the decision-making literature on judgmental anchors to develop a strategy for establishing challenging self-set goals. In experiments involving the generation of uses for common objects, we demonstrated that introducing an arbitrary and unreasonably high anchor significantly increased the value selected as a self-set goal. Self-efficacy and task performance also increased subsequent to the introduction of a high anchor. These results of anchoring goals occurred without reducing the goal commitment that is associated with self-set goals. Moreover, when anchored self-set goals were compared to assigned goals, they were found to have similar levels of performance and greater goal commitment. Discussion focused on the implications of anchoring goals for the processes and outcomes related to assigned and self-set goal-setting situations.
