Benefit-finding and growth is an important process across a range of medical populations. However, it has been understudied in the context of lifelong chronic conditions, such as spina bifida (SB). This study aimed to develop a new measure of benefit-finding and growth for youth with SB, confirm its factor structure, and examine its psychometric properties. To generate items for the new measure, 20 adolescents and young adults with SB completed qualitative interviews regarding their experience of living with SB. Interviews were coded for benefits. Questionnaire items were generated from these benefits, and an expert panel refined the wording of these items. The resultant 31-item measure was shared with six of the 20 participants for feedback and then piloted among 251 youth with SB. The factor structure of the measure was confirmed and reliability and convergent validity were assessed. Both a one- and four-factor structure were supported. The four factors include: Life Perspectives and Priorities, Personal Characteristics and Traits, Connections and Opportunities, and Problem Solving. Higher total and factor scores represent greater benefit-finding and growth. The measure demonstrated excellent internal consistency (α = 0.95). The new measure also showed significant positive correlations with optimism, positive affect, and life satisfaction. This study produced a measure of benefit-finding and growth for youth with SB. Clinically, information about what youth with SB perceive to be their areas of strength and growth from their condition provides crucial insight into which factors to enhance in this population.
