Measuring affective temperaments: a systematic review of validation studies of the Temperament Evaluation in Memphis Pisa and San Diego (TEMPS) instruments.

BACKGROUND: The assessment of affective temperaments has provided useful insights for the psychopathological understanding of affective disorders and for the conceptualization of bipolar spectrum disorders. The Temperament in Memphis Pisa and San Diego (TEMPS) instrument has been widely used in research, yet its psychometric properties and optimal factor structure are unclear. METHODS: The PubMed/MEDLINE, PsycINFO, and EMBASE electronic databases were searched from inception until March 15th, 2016. Validation peer-reviewed studies of different versions of the TEMPS performed in adult samples were considered for inclusion. RESULTS: Twenty-seven studies (N=20,787) met inclusion criteria. Several versions of the TEMPS have been validated in 14 languages across 15 countries. The 110-item self-reported version of the TEMPS has been the most studied version. Most studies (50%) supported a five factor solution although few studies performed confirmatory factor analyses. A five-factor solution has consistently been reported for the 39-item version of the TEMPS-A. Overall, evidence indicates that different versions of the TEMPS have adequate internal consistency reliability, while the TEMPS-A-110 version has acceptable test-retest reliability. The methodological quality of included studies varied. LIMITATIONS: A meta-analysis could not be performed due to the heterogeneity of settings and versions of the TEMPS utilized. CONCLUSIONS: Different versions of the TEMPS have been validated across different cultures. The short 39-item version of the TEMPS-A holds promise and merits further investigation. Culture-bound factors may influence the expression and/or assessment of affective temperaments with the TEMPS.

Sensory processing patterns, coping strategies, and quality of life among patients with unipolar and bipolar disorders

Objective: To compare sensory processing, coping strategies, and quality of life (QoL) in unipolar and bipolar patients; to examine correlations between sensory processing and QoL; and to investigate the relative contribution of sociodemographic characteristics, sensory processing, and coping strategies to the prediction of QoL. Methods: Two hundred sixty-seven participants, aged 16-85 years (53.6±15.7), of whom 157 had a diagnosis of unipolar major depressive disorder and 110 had bipolar disorder type I and type II, completed the Adolescent/Adult Sensory Profile, Coping Orientations to Problems Experienced, and 12-item Short-Form Health Survey version 2. The two groups were compared with multivariate analyses. Results: The unipolar and bipolar groups did not differ concerning sensory processing, coping strategies, or QoL. Sensory processing patterns correlated with QoL independently of mediation by coping strategies. Correlations between low registration, sensory sensitivity, sensation avoidance, and reduced QoL were found more frequently in unipolar patients than bipolar patients. Higher physical QoL was mainly predicted by lower age and lower sensory sensitivity, whereas higher mental QoL was mainly predicted by coping strategies. Conclusion: While age may predict physical QoL, coping strategies predict mental QoL. Future studies should further investigate the impact of sensory processing and coping strategies on patients’ QoL in order to enhance adaptive and functional behaviors related to affective disturbances.

Affective temperaments in general population: a review and combined analysis from national studies.

BACKGROUND: The aim of this study was to investigate the characteristics of affective temperaments in general non-clinical population in different countries METHOD: We performed a detailed search of published studies (one unpublished) investigating affective temperaments in non-clinical populations by administering the Temperament Evaluation of Memphis, Paris and San Diego Auto-questionnaire (TEMPS-A) in its 110-items version. We have included a total of six studies published from different countries (Argentina, Germany, Hungary, Korea, Lebanon, and Portugal) and one unpublished with preliminary data from Spain. We analyzed the combined data from the collected studies. RESULTS: We found significant gender differences, with men scoring higher in irritable and hyperthymic, and women in anxious, depressive and cyclothymic temperaments. Age had a significant effect in women with depressive temperament. Correlations among temperament scores have shown positive associations between depressive and anxious, and cyclothymic and irritable. CONCLUSIONS: There was a similarity in gender differences and the association between different affective temperaments. Our results indicate that affective temperaments show both universal and distinctive characteristics. LIMITATION: The sample populations in different countries were not homogeneous for age and socio-economic composition. In the Korean study of Kang et al. the version of the TEMPS was not validated.

The role of hyperventilation: hypocapnia in the pathomechanism of panic disorder

OBJECTIVE: The authors present a profile of panic disorder based on and generalized from the effects of acute and chronic hyperventilation that are characteristic of the respiratory panic disorder subtype. The review presented attempts to integrate three premises: hyperventilation is a physiological response to hypercapnia; hyperventilation can induce panic attacks; chronic hyperventilation is a protective mechanism against panic attacks. METHOD: A selective review of the literature was made using the Medline database. Reports of the interrelationships among panic disorder, hyperventilation, acidosis, and alkalosis, as well as catecholamine release and sensitivity, were selected. The findings were structured into an integrated model. DISCUSSION: The panic attacks experienced by individuals with panic disorder develop on the basis of metabolic acidosis, which is a compensatory response to chronic hyperventilation. The attacks are triggered by a sudden increase in (pCO2) when the latent (metabolic) acidosis manifests as hypercapnic acidosis. The acidotic condition induces catecholamine release. Sympathicotonia cannot arise during the hypercapnic phase, since low pH decreases catecholamine sensitivity. Catecholamines can provoke panic when hyperventilation causes the hypercapnia to switch to hypocapnic alkalosis (overcompensation) and catecholamine sensitivity begins to increase. CONCLUSION: Therapeutic approaches should address long-term regulation of the respiratory pattern and elimination of metabolic acidosis.

OBJETIVO: Os autores apresentam um modelo de transtorno do pânico que se baseia nos efeitos da hiperventilação aguda e crônica, característicos do subtipo respiratório de transtorno do pânico. O modelo é generalizado a partir desses efeitos. Ele integra três características da hiperventilação: a hiperventilação é uma resposta fisiológica à hipercapnia; a hiperventilação pode induzir ataques de pânico; a hiperventilação crônica representa um mecanismo protetor contra os ataques de pânico. MÉTODO: Revisão seletiva da literatura a partir da base de dados Medline. Foram selecionados relatos referentes à inter-relação entre transtorno do pânico, hiperventilação, acidose, alcalose, liberação de catecolaminas e sensibilidade a catecolaminas, sendo os achados estruturados de modo a formar um modelo integrado. DISCUSSÃO: Os ataques de pânico do transtorno do pânico desenvolvem-se com base numa acidose metabólica, que é uma resposta compensatória à hiperventilação crônica. Os ataques são desencadeados por um súbito aumento da pressão parcial de dióxido de carbono (pCO2), quando a acidose (metabólica) latente se manifesta pela acidose hipercápnica. A condição acidótica induz liberação de catecolaminas. A simpaticotonia não pode manifestar-se durante a fase de hipercapnia, pois o baixo pH diminui a sensibilidade às catecolaminas. As catecolaminas podem provocar pânico quando a hipercapnia comuta para uma alcalose hipocápnica devido à supercompensação pela hiperventilação, situação na qual a sensibilidade às catecolaminas liberadas começa a aumentar. CONCLUSÃO: As abordagens terapêuticas deveriam voltar-se para a regulação em longo prazo do padrão respiratório e a eliminação da acidose metabólica.
