Using Mixed-Methods to Evaluate “Transformation of Motivation” as a Construct Influencing Risk Communication among Families at Inherited Risk for Ovarian Cancer 公开
Zhao,Jingsong (Summer 2024)
Abstract
Inherited health conditions represent shared risk for families. Many have called for applying relational frameworks in considering how genetic risk communication could be motivated. Generally, these frameworks suggest concepts such as “transformation of motivation” (TM) holding that shared desires to preserve family relationships can prompt positive health steps that would not be taken on the proband’s own behalf. However, the TM construct that to date has been poorly operationalized. My overarching aim is to advance our understanding of how to measure the construct of TM. In Aim 1, I undertook a systematic review of 13 FGRC interventions identified between January 2010 to August 2023. This review aimed to address a research gap by examining how current intervention strategies align with theories at the individual, relational, and family-system levels. Additionally, evaluated the effectiveness of these strategies compared to standard-ofcare groups in fostering communication of inherited risk among families at higher risk of hereditary conditions. Aim 2 and Aim 3 studies represent a new methodological effort to bring conceptual clarity to the latent TM construct. Rather than relying on unvalidated measurements, I systematically analyzed whether survivors of ovarian cancer survivors’ natural patterns of use of a study website might serve as indicators of “we-ness” thought to underpin the TM construct. In aim 2, I found two factors that characterized survivors’ website engagement, one behavioral and one cognitive factor. In Aim 3, I found that “We”-talk were not associated with family closeness and family size. Yet, qualitative interpretations of interviews revealed relational talks from survivors, suggesting that “we”-talk may not be a reliable marker. Furthermore, high and low wetalkers did not differ in their discussion of TM-mapped content, except in their perception of family emotional closeness. In order to evaluate whether TM can be leveraged in behavior change interventions, we must develop rigorous assessment tools to characterize it. Future research needs to move beyond pronoun counts to consider survivor appraisal processes multiple family members’ perspectives on its occurrence, develop and test measures of relational thinking and their association with a variety of shared coping strategies (including health behaviors as the gold standard).
