The Ages & Stages Questionnaire: Social–Emotional: A validation study of a mother‐report questionnaire on a clinical mother–infant sample

Mother‐report questionnaires of infant socioemotional functioning are increasingly used to screen for clinical referral to infant mental health services. The validity of the Ages & Stages Questionnaire: Social Emotional (ASQ:SE; J. Squires, D. Bricker, K. Heo, & E. Twombly, 2002) was investigated in a sample of help‐seeking mothers with young infants. It was compared with independent observer‐rated dyadic interactions, and the quality of dyadic relationships was rated by expert clinicians. The ASQ:SE ratings also were compared with questionnaires on maternal psychological stress and distress. The ASQ:SE did not correlate significantly with either external ratings of dyadic interaction or clinically assessed relationship qualities, though the latter two were strongly associated with each other. In contrast, ASQ:SE scores were associated with questionnaires relating to maternal psychological distress. This was especially true for mothers classified as depressed. Furthermore, reports on the ASQ:SE were strongly predicted by maternal stress. The study points to some problems with the concurrent validity of the ASQ:SE in clinical samples. It also demonstrates a close link between mothers' psychological distress and their ratings of infant social and emotional functioning. Further research should investigate the extent to which the ASQ:SE specifically measures infant functioning or maternal distress, and how it functions in clinical versus nonclinical samples.

Lack of positive experiences and positive expectancies mediate the relationship between BAS responsiveness and depression

The anhedonic symptoms of depression have been linked to a lack of incentive responsiveness, which is a function of the Behavioral Activation System (BAS). Using structural equation modeling within the context of a cross-sectional design, we found that a lack of positive experiences and positive expectancies mediated the BAS-depression link among an undergraduate sample (N = 171). We tested the specificity of this model across four alternative models substituting negative experiences, negative expectancies, threat sensitivity, and symptoms of anxiety for their theoretical counterparts in the original model. In each case, the alternative model did not fit the data as well as our original model. This pattern of results is consistent with the position that a lack of positive experiences and positive expectancies uniquely mediate the relationship between the BAS and anhedonic symptoms of depression.
