Quality of life and clinical correlates in cognitively-able autistic adults: A special focus on sensory characteristics and perceived parental support

BACKGROUND

Quality of life (QoL) has been suggested as an indicator of outcomes in autistic adults. Factors associated with QoL in autistic individuals remain unclear. This study aims to examine the subjective QoL for autistic adults in Taiwan and investigate the determinants for different domains of QoL.

METHODS

The study comprised 90 autistic adults (aged 26.9, SD 7.3; males, 80.9%). We used Taiwanese version of World Health Organization Quality of Life-BREF to measure QoL. Four domains of QoL were compared with 61 non-autistic controls, including physical, psychological, social, and environment. To identify the correlates of QoL domains, we assessed IQ, personality trait, family support, anxiety/depressive symptoms, autistic severity, and sensory symptoms by various questionnaires, and assessed their association with QoL by correlation analyses and model selection.

RESULTS

Our results showed that autistic adults reported lower QoL on the World Health Organization Quality of Life (WHOQOL)-BREF across all domains. QoL was significantly associated with autistic symptom severity, harm avoidance, family support, sensory symptoms, anxiety, and depression, but not intelligence. Model selections revealed male sex, poor paternal support, autism severity, depression, anxiety, and sensory symptoms were associated with specific QoL domains.

CONCLUSION

Findings supported lower QoL in autistic adults. Modifying the QoL correlates may improve life quality in autistic adults. Furthermore, our findings revealed the importance of sensory symptoms and paternal support in QoL of autistic adults, which was a novel finding in this population.

Development and validation of TreatHSP-QoL: a patient-reported outcome measure for health-related quality of life in hereditary spastic paraplegia

BACKGROUND

Hereditary spastic paraplegia (HSP) is a rare neurodegenerative disease that lacks specific and validated patient-centered outcome measures (PCOMs). We aimed to develop and validate a health-related quality of life (HRQoL) questionnaire specific to HSP ("TreatHSP-QoL") that could be used as a PCOM.

RESULTS

The pilot-items of the TreatHSP-QoL (45 five-level Likert scale items, with values per item between 0 and 4) were developed based on a qualitative data analysis of 54 semi-structured interviews, conducted in person with 36 HSP patients and 18 caregivers. It was then reduced and modified through the validation process to 25 items. The main validation was performed using the online questionnaire in 242 HSP patients and 56 caregivers. The exploratory factor analysis defined five subdomains. Cronbach's alpha ranged from 0.57 to 0.85 for the subdomains and reached 0.85 for the total score. The test-retest Pearson correlation reached 0.86 (95% Confidence Interval (CI) [0.79, 0.91]). Pearson correlations with the EuroQol-5 Dimension (5 levels) (EQ-5D-5L) and Friedreich Ataxia Rating Scale-Activities of Daily Living (FARS-ADL) questionnaires varied strongly among the subdomains, with the total scores reaching 0.53 (95% CI [0.42, 0.61]) and -0.45 (95% CI [- 0.55, - 0.35]), respectively. The caregiver-patient response Pearson correlation ranged between 0.64 and 0.82 for subdomains and reached 0.65 (95% CI [0.38, 0.81]) for the total score.

CONCLUSIONS

TreatHSP-QoL can be used in high-quality clinical trials and clinical practice as a disease-specific PCOM (i.e., HRQoL measure) and is also applicable as a proxy questionnaire. Score values between 0 and 100 can be reached, where higher value represents better HRQoL. The Pearson correlations to the EQ-5D-5L and FARS-ADL support the additional value and need of HSP-specific PCOM, while non-specific QoL-assessment and specific clinical self-assessment tools already exist. All in all, the results demonstrate good validity and reliability for this new patient-centered questionnaire for HSP.
