In this article, we examine the psychometric properties of the PERS subscale and composite scores in an adult community sample (N = 428), and develop an 18-item short form of the measure (PERS–S). The PERS and PERS–S are designed to assess the typical ease of activation, intensity, and duration of one's emotional responses, and do so for positive and negative emotions separately. Our confirmatory factor analyses supported that the PERS and PERS–S both had the same theoretically congruent factor structure, and that all subscale and composite scores displayed high internal consistency reliability. Correlations with scores from established measures of psychopathology and emotion regulation also supported the validity of PERS and PERS–S scores. Our data therefore suggest that the PERS–S subscale and composite scores retain the psychometric strengths of their longer PERS counterparts. We conclude that both forms of the measure have good utility. Clinical and research applications are discussed.

Several self-report measures of emotion regulation ability exist, but many are inconsistent with contemporary emotion regulation theory, and none comprehensively assess this construct across both negative and positive emotions. In this paper, we report our attempt to remedy these measurement limitations by developing and validating the Perth Emotion Regulation Competency Inventory (PERCI), a 32 item self-report questionnaire that measures emotion regulation ability as it is defined by the extended process model of emotion regulation. In Study 1, our confirmatory factor analyses in a sample of adults (N = 231) suggested that the PERCI had a factor structure consistent with its theoretical basis and could separately measure people's ability to regulate their negative and positive emotions. All subscale and composite scores had high internal consistency reliability. Study 2 (N = 1175) replicated these findings with respect to factor structure and internal consistency reliability, and correlational or regression analyses with measures of psychopathology, emotion regulation processes, alexithymia, and interpersonal attachment style also supported the validity of the PERCI. We conclude that the PERCI appears to have strong psychometric properties. Clinical and research implications are discussed.

It is a widely used measure of emotion regulation, but its factor structure has rarely been examined outside of university student samples, and some authors have recently questioned its factorial validity in general community samples. In this study, we examine the psychometric properties of the ERQ (original English version) in 3 Australian general community samples (N = 300, 400, 348). Confirmatory factor analyses in each sample demonstrated that the traditional 2-factor model (comprised of cognitive reappraisal and expressive suppression factors) was replicable and an excellent fit to the data. In all samples, ERQ cognitive reappraisal (α = .89–.90) and expressive suppression (α = .76–.80) scores had acceptable to excellent levels of internal consistency reliability. As expected, cognitive reappraisal scores were significantly negatively correlated with psychological distress and alexithymia, whereas expressive suppression scores were significantly positively correlated with psychological distress and alexithymia. We conclude that, similar to previous findings in student samples, the ERQ has strong psychometric properties in general community samples and can therefore be used confidently regardless of participants’ student status.
The psychometric assessment of alexithymia: Development and validation of the Perth Alexithymia Questionnaire, 2018

Its assessment is of clinical interest because people who have difficulty processing their negative and positive emotions are more vulnerable to developing psychopathology symptoms, however, existing alexithymia measures cannot comprehensively assess the construct across both negative and positive emotions. In this paper, we attempt to remedy these measurement limitations by developing and validating a new 24-item self-report measure, the Perth Alexithymia Questionnaire (PAQ), which is based on the attention-appraisal model of alexithymia. In Study 1, our confirmatory factor analyses in a sample of 231 adults suggested that the PAQ had a factor structure consistent with its theoretical basis; it could separately measure all components of the construct and do so across negative and positive emotions. All subscale and composite scores had high internal consistency reliability. Study 2 (N = 748) replicated these findings with respect to the PAQ's factor structure and internal consistency reliability, and statistical comparisons with measures of psychopathology and emotion regulation supported the PAQ's concurrent and discriminant validity. Our data therefore suggest that the PAQ has strong psychometric properties as a measure of alexithymia. Clinical and research applications are discussed.

We examined the scale’s psychometric properties in Australian nonclinical (N=428) and psychiatric (N=156) samples. In terms of factorial validity, confirmatory factor analyses found the traditional 3-factor correlated model (DIF, DDF, EOT) to be the best and most parsimonious solution, but it did not reach adequate levels of goodness-of-fit in either sample. Several EOT items loaded poorly on their intended factor, and a reverse-scored item method factor was present; the factor structure of the scale was invariant across both samples. A higher-order factor model (with a single higher-order factor) was slightly inferior to the correlated models, but still tenable. The total scale score and DIF and DDF subscales displayed sound internal consistency, but the EOT subscale did not. We conclude that the TAS-20 has, for the most part, adequate psychometric properties, though interpretation should focus only on the total scale score and DIF and DDF subscales; we recommend the EOT subscale score not be used. Implications for clinical use and future revision of the scale are discussed.

We attempt to resolve this definitional uncertainty in two ways. Firstly, we trace the development of the alexithymia construct, focusing particularly on what we call the Toronto and Amsterdam models, and examine a body of empirical research that shows strong support for the hypothesis that alexithymia consists of three components (difficulty identifying feelings, difficulty describing feelings, and externally orientated thinking). Based on these components, we formulate an alternate theoretical model of alexithymia, the attention-appraisal model of alexithymia, that aligns alexithymia theory with recent advances in the broader emotion regulation field. Secondly, we examine the construct’s latent structure by factor analysing data from multiple psychometric measures administered to a community sample (N = 368). Our results suggest statistical support for our model, rather than the Toronto or Amsterdam models. We end by discussing how our model accounts for several unresolved issues within the alexithymia field, including the construct’s relation to imaginal capacities and emotional reactivity, whether alexithymia is a deficit or a defence, how it might be addressed in psychiatric treatment, and the discordance that has existed between alexithymia theory and alexithymia measurement.
