The healthy habits questionnaire (HHQ): Validation of a measure designed to assess problematic influential behaviours amongst families of children living with obesity or a risk of developing obesity.

Abstract

The 48-item Healthy Habits Questionnaire (HHQ-48) was developed to (1) monitor positive changes in family lifestyles following engagement in the Parents Plus Healthy Families (PP-HF) parent training programme and (2) be utilised as a standalone measure in clinical settings to identify and track problematic influential behaviours amongst families of children in weight-management services. This study aimed to develop and validate a brief version of the HHQ-48. The scale was administered to a cross-sectional community sample (n = 480), and on two occasions to a control sample (n = 50) and an experimental sample (n = 40) from a randomised controlled trial (RCT) of the PP-HF programme to assess test-retest reliability and sensitivity to change respectively. Exploratory and confirmatory factor analysis showed that a 23-item, 4-factor version of the HHQ (i.e., the HHQ-23) best fit the data. The scale and factor subscales had good internal consistency and test-retest reliability. They also had good concurrent and construct validity shown by significant correlations with another scale that assessed lifestyle issues, and scales that assessed parenting satisfaction, family functioning, and children's strengths and difficulties. The HHQ-23 was sensitive to change following parents completing the PP-HF programme. The HHQ-23 may, therefore, be used to monitor positive changes in family lifestyles following engagement in the PP-HF parent training programme. The HHQ-23 also shows promising potential as a standalone screening measure or as part of a larger battery of screening assessments in paediatric weight-management services.
