Continuity in primary school children's eating problems and the influence of parental feeding strategies

Eating problems are highly prevalent and seem to show continuity in children. Nevertheless, the effect of different maternal and paternal feeding practices on changes in these problems is not fully understood yet. This study examines short-term continuity in primary school children's overeating, loss of control (over eating), restraint and concerns (about eating, body shape and weight) and the predictive value of parental feeding strategies on change in these eating problems. Children (8-12 years, n = 613, 46.5 % girls) completed the Child Eating Disorder Examination Questionnaire (ChEDE-Q) twice with the second measurement (T2) taking place 6 months after the first (T1). Parents (n = 714, 57.7 % mothers) completed the Child Feeding Questionnaire (CFQ) at T1 to assess the level of controlling feeding strategies. More overeating, restraint and concerns at T1 predicted higher levels of the same eating problems 6 months later, whereas more of loss of control at T1 predicted lower levels of loss of control 6 months later. Additionally, the interaction between maternal pressure and the gender of the child was predictive for increases in overeating, whereas the interaction between paternal monitoring and gender of the child was a marginally significant predictor for decreases in overeating. These findings point to the possible negative and positive effects of parental feeding practices as well as to the possible larger influence of mothers on their daughters' and of fathers on their sons' eating behaviors. The importance of studying mothers and fathers, as well as daughters and sons, and of including different feeding strategies and eating problems is discussed

Psychometric Properties of the BIS/BAS Scales and the SPSRQ in Flemish Adolescents

Objective: Gray’s Reinforcement Sensitivity Theory (RST) is a frequently used model of personality that is relevant to the period of adolescence. However, the psychometric properties of the most frequently used questionnaires to measure the RST-constructs, namely the Behavioural Inhibition System and Behavioural Activation System Scales (BIS/BAS Scales) and the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), are rarely examined in samples of adolescents. Therefore, the goal of the present study was to examine the two-factor structure, reliability and convergent validity of the BIS/BAS Scales and SPSRQ in a Flemish adolescent community sample.  Method: A sample of 579 adolescents (39.5% boys; 14–19 years) was recruited. The proposed two-factor structure was assessed using Exploratory Structural Equation Modeling. Reliability was evaluated using internal consistency and construct validity was examined with the correlations between the two questionnaires and with the Temperament and Character Inventory–short form (TCI-SF).  Results: After the removal of problematic items, and the addition of correlated errors, all indices indicated a good fit for the two-factor structure of the modified BIS/BAS Scales. For the modified SPSRQ, three fit indices indicated a good model fit, while a fourth fit index was slightly below the cut-off score of an adequate model fit. Internal consistency of both questionnaires was sufficient. In general, the associations with scales of the TCI-SF were as expected, with positive correlations between BIS-related scales, and between BAS-related scales of all three instruments.  Discussion: In Flemish adolescents, the use of a two-factor model to analyze data gathered with the modified BIS/BAS Scales or modified SPSRQ seems appropriate

Sensitivity for cues predicting reward and punishment in young women with eating disorders

Increasing evidence shows that sensitivity to reward (SR) and punishment (SP) may be involved in eating disorders (EDs). Most studies used self-reported positive/negative effect in rewarding/punishing situations, whereas the implied proneness to detect signals of reward/punishment is largely ignored. This pilot study used a spatial orientation task to examine transdiagnostic and interdiagnostic differences in SR/SP. Participants (14–29 years) were patients with anorexia nervosa of restricting type (AN-R, n = 20), binge/purge ED group [AN of binge/purge ty pe and bulimia nervosa (n = 16)] and non-symptomatic individua ls (n = 23). Results revealed stronger difficulties to redirect attention away from signals of rewards in AN-R compared with binge/purge EDs, and inge/purge EDs showed stronger difficulties to direct attention away from signals of punishment compared with AN-R. Findings demonstrate inter diagnostic differences and show that the spatial orientation task is sensitive for individual differences in SP/SR within the context of EDs, thereby sustaining its usefulness as behavioural measure of reinforcement sensitivity.
