Sequential Phases of Qualitative Analysis

Phase		N (N=136 dyads)	Analytic Approach
1.	Explore aggregate perspectives on the intervention	136 adolescents (A) 136 caregivers (CG)	Content analysis: Code summary of adolescent; caregiver perspectives on intervention, e.g. liked/disliked; easy/hard; topic preferences, program strategies, etc.
2.	Compare perspectives between weight loss group	Weight loss group 50 As; 50 CGs Weight gain group 86 As; 86 CGs	Content analysis: Adolescent and caregiver groups stratified into two groups, those who lost versus those who gained weight. Perspectives on intervention components compared.
3.	Explore dyadic relationships	136 A-CG dyads	Secondary coding & pattern analysis: Dyad (A-CG) perspectives on their interactions; patterns organized into a five types.
4.	Compare dyadic relationships using “extreme case” comparison	13 A-CG dyads (top 10%- ‘biggest losers’)^± 13 A-CG dyads (bottom 10%- ‘biggest gainers’)^±±	Interpretive cross-case analysis: Dyads stratified into top and bottom 10% of the sample for weight change; themes associated with success/lack of success for weight loss identified.

^±

Top = adolescents who lost the most weight (lost on average 10.4 pounds);

^±±

Bottom = adolescents who lost the least (gained on average 9.8 lbs.)
