Treatment Beliefs of Children and Adolescents With Chronic Diseases: Development of the Rehabilitation Treatment Beliefs Questionnaire for Children and Adolescents.

OBJECTIVE: Rehabilitation is an important component in the health care of children and adolescents with chronic diseases and aims at supporting patients' self-regulation for dealing with the disease. Patients' beliefs about illness and treatment are core elements in the self-regulation process. While questionnaires measuring illness beliefs for children and adolescents exist, questionnaires about their rehabilitation-related treatment beliefs are lacking. We therefore developed a questionnaire to assess the rehabilitation-related treatment beliefs of children and adolescents with chronic diseases (Rehabilitation Treatment Beliefs Questionnaire, RTBQ) and tested its psychometric properties. METHODS: Ahead of their rehabilitation, children and adolescents, aged 12-17 years, answered 129 items, which were developed based on previous qualitative findings exploring children and adolescents' rehabilitation-related treatment beliefs. Psychometric testing included item analyses, exploratory factor analysis, internal consistency and bivariate correlations of the extracted scales, and the discriminatory power and difficulty of the final items. RESULTS: The sample consisted of 170 participants with a mean age of 14.3 years (SD = 1.6); 53.5% were female. After item analyses, 47 items remained for the exploratory factor analysis which revealed 22 items allocated to 4 scales: "expectations of communication and interaction," "expectations of the treatment process," "expectations of treatment success and sustainability," and "expectations of one's own role in the rehabilitation process." The psychometric properties were acceptable to good. CONCLUSIONS: The RTBQ assesses various dimensions of rehabilitation-related treatment beliefs of children and adolescents with chronic diseases. While first psychometric results are promising, further psychometric testing is needed.

Rehabilitation-related treatment beliefs in adolescents: A qualitative study.

BACKGROUND: Medical rehabilitation plays an important role in the health care of chronically ill children and adolescents. During medical rehabilitation, supporting illness-related self-regulation is a central goal. Beliefs about illness and beliefs about treatment are core elements of patients' self-regulation, and there is evidence that these beliefs are relevant predictors of different health- and treatment-related outcomes such as adherence. However, little is known about adolescents' beliefs about rehabilitation. This study therefore explores adolescents' treatment beliefs in the context of inpatient medical rehabilitation. METHODS: A qualitative study was conducted in a German rehabilitation clinic for children and adolescents. Using a purposive sampling method, 13 adolescents (12-16 years old) were recruited. Semi-structured, audiotaped interviews were conducted and analysed using content analysis. RESULTS: Results demonstrate that adolescents have differentiated rehabilitation-related treatment beliefs. Twelve themes, with various subthemes, emerged, which include access to and knowledge about rehabilitation, the rehabilitation-related individual position and normative aspects, expectations of oneself, as well as in respect of the social context (fellow patients, contact with family and friends), expectations of the structure, process and outcome of rehabilitation, concerns and barriers and emotional aspects. CONCLUSIONS: Our explorative study revealed a broad range of rehabilitation-related treatment beliefs in adolescents, indicating parallels, but also differences, to research results with adults. Treatment beliefs are assumed to be an influencing factor for various health- and treatment-related outcomes. Thus, implications of our findings for clinical practice and further research are discussed.

Contextual factors of self-regulation in children and adolescents with chronic diseases - a qualitative analysis.

BACKGROUND: In recent decades, the prevalence of chronic diseases in children and adolescents has increased significantly. Contextual factors play a central role in the self-regulation of chronic diseases. They influence illness and treatment representations, disease management, and health outcomes. While previous studies have investigated the influence of contextual factors on children's beliefs about their illness, little is known about subjective contextual factors of treatment representations of children and adolescents with chronic diseases, especially in the context of rehabilitation. Therefore, the aim of this qualitative analysis was to examine the contextual factors reported by chronically ill children and adolescents in relation to their treatment representations. Furthermore, we aimed to assign the identified themes to classifications of environmental and personal contextual factors in the context of the International Classification of Functioning, Disability and Health (ICF). METHODS: Between July and September 2018, semi-structured interviews were conducted with N = 13 children and adolescents in rehabilitation to explore their rehab-related treatment representations and associated contextual factors. The interviews started with an open narrative question about expectations and beliefs about rehabilitation, followed by further detailed questions. The interviews were recorded on audio tape, transcribed, and analysed using thematic content analysis. RESULTS: Participants raised six themes associated with their rehab-related treatment representations that were interpreted as contextual factors: the living situation before rehabilitation, the idea of rehabilitation, previous solution attempts, rehab pre-experiences, information that the children and adolescents received from the clinic or sought themselves, and the assumed attitudes of their parents concerning rehabilitation. All the themes could be assigned to the classification of environmental and personal factors in the context of the ICF for children and youth. CONCLUSIONS: Although contextual factors have an important impact on self-regulation, little attention is paid to their investigation. Personal and environmental factors probably influence patients' treatment representations in terms of expectations and concerns as well as emotions regarding the treatment. Considering contextual factors could lead to the more appropriate allocation of medical care and the better customisation of treatment.

Obesity in patients with craniopharyngioma: assessment of food intake and movement counts indicating physical activity.

Patients with childhood-onset craniopharyngioma (CP) often suffer from obesity. We evaluated two important etiological factors of obesity development, energy intake and physical activity. Energy intake was supposed to be high due to a disturbed hypothalamic regulation of appetite. We used a validated nutritional diary to determine the 1-wk food intake in 27 CP patients (12 with intrasellar tumors and 15 with hypothalamic tumors) and 1027 controls who were a representative sample of the 7- to 16-yr-old German population. In 2 accelerometry settings, we determined movement counts indicating physical activity. Nineteen CP patients were comparable to 26 controls for age and body mass index. One setting was a clinical one during weight reduction; the other was an out-patient setting. Daily energy intake was 1916 +/- 677 kcal (mean +/- SD) in intrasellar CP patients, 2075 +/- 877 kcal in hypothalamic CP patients, and 2476 +/- 815 kcal in non-CP controls. Patients suffering from CP showed fewer movement registrations [clinical setting, 228 vs. 298 cpm for obese controls (P = 0.01); out-patient setting, 228 vs. 282 cpm for controls (P = 0.08)]. Differences were most pronounced during leisure time (382 cpm in CP patients vs. 546 cpm in obese controls; P = 0.002; clinical setting). Our findings suggest that reduced physical activity, rather than increased energy intake, in CP patients is responsible for the obesity development noted in these subjects.
