Factor structure and convergent validity of the Derriford Appearance Scale-24 using standard scoring versus treating 'not applicable' responses as missing data: a Scleroderma Patient-centered Intervention Network (SPIN) cohort study

Multi-Organ System Screening, Care, and Patient Support in Systemic Sclerosis

Systemic sclerosis (SSc) is a heterogenous systemic autoimmune disease of complex multi-organ manifestations with a disease-specific mortality of >50%. The patient journey is fraught with severe, diverse, and diffuse physical impairment, psychological burden, and diminishing health-related quality of life. SSc remains unfamiliar to many clinicians. Delayed/misdiagnosis, inadequate screening, and attention for common complications with potentially preventable disability/death contribute to patients feeling isolated and unsupported. We present actionable standards including screening, anticipatory guidance, and counseling in patient-centered SSc-care emphasizing psycho-social health as the central goal, whereas robust vigilance and efforts to improve biophysical health and survival are imperatives that support this goal.

Weight management strategies in Middle-Aged Women (MAW): Development and validation of a questionnaire based on the Oxford Food and Activity Behaviors Taxonomy (OxFAB-MAW) in a Portuguese sample

Background

The Oxford Food and Activity Behaviors (OxFAB) taxonomy systematize the cognitive-behavioral strategies adopted by individuals who are attempting to manage their weight. The present study aimed to (1) develop a questionnaire based on the OxFAB taxonomy, specifically adapted for middle-aged women-the OxFAB-MAW-stage of life and sex, which present a high incidence of obesity, (2) assess the psychometric properties of this tool, and (3) evaluate the discriminative power of the OxFAB-MAW (normal weight vs. obesity).

Methods

Overall, 1,367 Portuguese middle-aged women between 45 and 65 years (M = 52.3, SD = 5.15) filled in a sociodemographic, health, and menopause-related questionnaire, as well as the OxFAB-MAW.

Results

Confirmatory factor analysis demonstrated an acceptable model fit (comparative fit index = 0.928, Tucker-Lewis index = 0.913, root mean square error of approximation = 0.072, and standardized root mean square residual = 0.054). Five domains with one item were grouped into other domains, and the Weight Management Aids domain was also removed. The OxFAB-MAW showed factorial, convergent, discriminant, and external validity, as well as composite reliability.

Conclusion

The OxFAB-MAW questionnaire is a valid, reliable, and theory-driven tool for assessing weight management strategies in middle-aged women, being able to discriminate between clinical and non-clinical groups (normal weight vs. obesity) in several domains. This instrument can be used to gather valid and reliable data, useful in both research and clinical settings (especially focused on structuring interventions and preventive obesity programs within this specific life cycle stage).

A systematic review of body image measures for people diagnosed with head and neck cancer (HNC)

PURPOSE

Head and neck cancer (HNC) is a relatively common cancer which causes a significant health burden, impacting individuals physically and psychologically. HNC treatment may result in facial disfigurement, eating and communication difficulties, and body image disturbances. We aimed to (1) identify HNC-specific patient-reported outcome measures (PROMs) used to assess body image, (2) evaluate their conceptual coverage, (3) appraise their development process and psychometric properties, and (4) determine appropriate body image PROM(s) for use in the HNC setting.

METHODS

Online databases were searched (July 2007-July 2017) for studies that assessed body image in patients with HNC. Studies were screened for eligibility. In addition, we searched three PROM databases for relevant PROMs. From available body image frameworks, we compiled a conceptual schema consisting of 18 clinically relevant body image issues important in the HNC setting, against which PROMs were assessed. Selected measures were appraised for psychometric characteristics, content, and readability.

RESULTS

A total of 245 records were retrieved. 18 studies with PROMs met our inclusion criteria, reporting eight PROMs. The PROM databases searched yielded 62 measures. After screening, eleven measures were short-listed and appraised. The Derriford Appearance Scale (DAS)-59, DAS-24, and body image scale (BIS) cover > 55% of issues within the body image conceptual schema; were developed based on literature, patient interviews, and clinician opinions; and have evidence of internal consistency (Cronbach alpha > 0.7), validity, and responsiveness.

CONCLUSIONS

We recommend the DAS-24 and BIS as having adequate coverage of HNC-related issues, and suitable for use in future research.
