Therapy Adherence and Emotional Awareness and Regulation in Persons With Human Immunodeficiency Virus

Alexithymia Among People Living with HIV: A Scoping Review

The present scoping review aimed to identify studies that investigated alexithymia, defined as a difficulty in identifying and describing one's own emotions, in people living with HIV (PLWH).A literature search, in line with the guidelines of PRISMA-ScR, was conducted in the following bibliographic databases: PubMed, PsycINFO, and Web of Science. The databases were queried using the following strings (using Boolean operators): ("alexithymia" OR "alexithymic") AND ("HIV" OR "Human Immunodeficiency Virus"). In line with the eligibility criteria, fourteen articles were found.Ten studies showed the involvement of alexithymia in disease severity (e.g., viral load levels), and adherence to antiretroviral therapy. Three studies revealed an association between alexithymia and cardiovascular disease, and three studies highlighted the implication of alexithymia in cognitive impairment.This review revealed the complex role of alexithymia in HIV disease. A careful clinical assessment of the emotional regulation process of PLWH can provide useful prognostic information.

Building a new scale to measure worries about oral hygiene self-management in vulnerable older adults

OBJECTIVE

This paper describes a new scale to measure worries about self-management of oral hygiene in low-income older adults.

BACKGROUND

Oral hygiene that prevents oral diseases and worsening of chronic conditions improves with instruction, but other cognitive/emotional factors impede oral hygiene practice especially among older adults. Many scales measure dental anxiety, but none measures oral hygiene self-management worries.

MATERIALS AND METHODS

Formative research with diverse older adults 55-95 in low-income housing identified scale items. A 23-item scale was tested in a pilot intervention study (n = 84) and formalised with a new sample (N = 331).

RESULTS

In both studies, PCA/factor analysis produced two subscales: (a) worries about cleaning teeth and (b) consequences of cleaning. Chronbach's alpha coefficient evaluated internal consistency, and Pearson's r and Kendall tau/Spearman's rho evaluated scale predictability, convergent and divergent validity. The scale and subscales showed good internal consistency in both studies (over 0.90) and stability T0 0.90; T1: 0.90). In the larger sample, statistically significant correlations between the scale, subscales; plaque score, and similar scales (perceived risk of oral health problems, and fears of oral diseases) demonstrated convergent validity. For divergent validity, the worries scale, not the GOHAI, a similar scale measuring oral health life quality, was associated with Plaque Score. Each scale was associated with different mediators suggesting different constructs.

CONCLUSION

The overall scale has good internal consistency, test-retest reliability, predictability and convergent and divergent validity. It captures a psycho-emotional construct useful in oral health research and hygiene education with older adults.

Twenty-five years with the 20-item Toronto Alexithymia Scale

OBJECTIVE

Twenty-five years ago, this journal published two articles reporting the development and initial validation of the 20-Item Toronto Alexithymia Scale (TAS-20). Since then the literature on alexithymia has burgeoned with the vast majority of this research using the TAS-20, including multiple language translations of the scale.

METHOD

In this article we review the psychometric literature evaluating various aspects of the reliability and validity of the TAS-20 and examine some of the controversies surrounding the scale and the construct it assesses. We reflect on the ways in which the TAS-20 has advanced the measurement of the construct and theory of alexithymia. We also discuss recent developments and some future directions for the measurement of alexithymia.

RESULTS

Although not without some controversy, the preponderance of the accumulated evidence over a 25-year period supports various aspects of the reliability and validity of the TAS-20, including findings from confirmatory factor analytic and convergent and discriminant validity studies which are consistent with Nemiah et al.'s (Nemiah et al., 1976 [3]) and Taylor and colleagues (Taylor et al., 1997 [9]) theoretical formulations and definition of the alexithymia construct.

CONCLUSIONS

Based on the accumulated empirical evidence of 25 years, we conclude that the TAS-20 is a reliable and valid instrument and accurately reflects and measures the construct as it was originally defined by Nemiah et al. Nemiah et al. (1976) [3] as composed of deficits in affect awareness and expression and pensée opératoire (operational thinking). Clinicians and researchers can use the TAS-20 to confidently measure alexithymia, the roots of which have foundations in psychosomatic medicine.
