Identifying Factors that Facilitate Treatment Adherence in Cystic Fibrosis: Qualitative Analyses of Interviews with Parents and Adolescents.

Cystic fibrosis (CF) is a progressive, genetic disease affecting multiple organ systems. Treatments are complex and take 2-4 h per day. Adherence is 50% or less for pulmonary medications, airway clearance, and enzymes. Prior research has identified demographic and psychological variables associated with better adherence; however, no study has extensively identified facilitators of treatment adherence (e.g., adaptive behaviors and cognitions) in a sample of parents and adolescents. Forty-three participants were recruited from four CF centers as part of a larger measurement study. Participants included 29 parents (72% mothers; 72% Caucasian) and 14 adolescents (ages 11-20, 64% female, 71% Caucasian). Participants completed semi-structured interviews to elicit barriers to adherence. However, facilitators of adherence naturally emerged, therefore indicating need for further exploration. Interviews were audiotaped, transcribed and content-analyzed in NVivo to identify those behaviors and beliefs that facilitated adherence, using a phenomenological analysis. Frequencies of these themes were tabulated. Nine themes emerged, with individual codes subsumed under each. Themes included social support, community support, organizational strategies, "intrinsic characteristics," combining treatments with pleasurable activity, flexibility, easier or faster treatment, prioritizing treatments, and negative effects of non-adherence. Results demonstrated the importance of identifying strategies that positively affect adherence. Interventions that are strength-focused, build on prior success, and utilize positive models generated by those who have successfully integrated CF treatments into their lives are more likely to be efficacious.

Misunderstandings, misperceptions, and missed opportunities: Perspectives on adherence barriers from people with CF, caregivers, and CF team members.

OBJECTIVE: To identify differences in perspectives of people with cystic fibrosis (PwCF) and caregivers versus healthcare providers on adherence barriers. Mismatched perspectives may lead to miscommunication and missed opportunities to reduce barriers and improve CF outcomes. METHODS: PwCF, caregivers, and CF providers completed audio-taped, semi-structured interviews about adherence barriers. Interviews were transcribed and coded for themes. Themes were reviewed to identify when PwCF-caregiver perspectives differed from providers'. RESULTS: Participants included 14 adolescents with CF (mean age = 15.89 years, 64 % female, 71 % Caucasian), 14 adults with CF (mean age = 30.03 years, 64 % female, 57 % Caucasian), 29 caregivers (76 % female; 72 % Caucasian), and 42 providers. Four barriers were identified that could generate miscommunication between PwCF-caregivers and providers: Tired = Fatigued/Sleepy versus Tired = Burnout, Vacation and Travel, Knowledge and Skills About CF Regimen, and Daily Habits or Routines. PwCF and caregivers used similar words as providers, but conceptualized barriers differently. PwCF and caregivers discussed barriers pragmatically, however, providers viewed certain barriers more abstractly or unidimensionally, or did not discuss them. CONCLUSIONS: PwCF-caregivers and providers may not align in how they discuss barriers, which may contribute to miscommunication about adherence challenges. PRACTICE IMPLICATIONS: Patient-centered communication strategies may enhance providers' understandings of PwCF-caregiver perspectives on barriers and facilitate adherence interventions.

Parent knowledge of disease management in cystic fibrosis: Assessing behavioral treatment management.

BACKGROUND: Cystic fibrosis (CF) is a life-shortening, burdensome disease requiring complex knowledge to manage the disease. Significant gaps in knowledge have been documented for parents, which may lead to unintentionally poor adherence and insufficient transfer of treatment responsibility from parents to adolescents. There are no current, validated measures of parent knowledge for this population and there are no measures that assess the knowledge required for day-to-day behavioral management of CF. We assessed the psychometric properties of the parent version of the Knowledge of Disease Management-Cystic Fibrosis measure (KDM-CF-P) using data from iCARE (I Change Adherence and Raise Expectations), a randomized control adherence intervention trial. METHODS: A total of 196 parents in the iCARE standard care/control arm completed 35 items assessing their knowledge of disease management at their 12-month study visit, prior to beginning the intervention. Items were eliminated from the measure if they met the threshold for ceiling effects, were deemed clinically irrelevant, or did not correlate well with their intended scale. Item-to-total correlations, confirmatory factor analysis, discriminant function, reliability, and convergent validity were calculated. RESULTS: The KDM-CF-P (19 items) demonstrated internal consistency of KR20 = 0.60 on each scale and a two-scale structure. Convergent validity for knowledge scores was found with maternal education, family income, and type of medical insurance. Parents correctly answered approximately 85% of items on the KDM-CF-P. CONCLUSIONS: The KDM-CF-P psychometrics support a two-scale measure with clinical utility. It is useful for assessing gaps in knowledge that can be remediated through individualized, tailored interventions.

Family dynamics and psychosocial functioning in children with SCI/D from Colombia, South America.

OBJECTIVE: The purpose of this study was to examine the connections between family dynamics and the psychosocial functioning of children with spinal cord injuries and disorders (SCI/D). DESIGN: Cross-sectional. SETTING: Participants were recruited from communities in Neiva, Colombia. PARTICIPANTS: Thirty children with SCI/D and their primary caregiver participated. Children were between 8 and 17 years of age, and had sustained their injury at least six months prior to data collection. INTERVENTIONS: NA. OUTCOME MEASURES: Participating children completed measures assessing their own psychosocial functioning (Children's Depression Inventory, Revised Children's Manifest Anxiety Scale-2, Pediatric Quality of Life Inventory), and their primary caregiver completed measures of family dynamics (Family Adaptability and Cohesion Evaluation Scale- Fourth Edition, Family Communication Scale, Family Assessment Device- General Functioning, Family Satisfaction Scale, Relationship-Focused Coping Scale). RESULTS: A correlation matrix showed a number of significant bivariate correlations between child and family variables, and three multiple regressions showed that family satisfaction, empathy, and flexibility significantly explained 27% of the variance in child worry; family satisfaction and communication explained 18% of the variance in child social anxiety; and family cohesion and communication explained 23% of the variance in child emotional functioning. CONCLUSIONS: These findings highlight the importance of rehabilitation professionals considering the association between family dynamics and the psychosocial functioning of children with SCI/D when working with this population.
