[Evidence-Based Psychological Treatments for Adults: A Selective Review]

Evidence-Based Psychological Treatments for Adults: A Selective Review. BACKGROUND: Psychological treatments have shown their efficacy, effectiveness, and efficiency in dealing with mental disorders. However, considering the scientific knowledge generated in recent years, in the Spanish context, there are no updating studies about empirically supported psychological treatments. The main goal was to carry out a selective review of the main empirically supported psychological treatments for mental disorders in adults. METHOD: Levels of evidence and degrees of recommendation were collected based on the criteria proposed by the Spanish National Health System (Clinical Practice Guidelines) for different psychological disorders. RESULTS: The results indicate that psychological treatments have empirical support for the approach to a wide range of psychological disorders. These levels of empirical evidence gathered range from low to high depending on the psychological disorder analysed. The review indicates the existence of certain fields of intervention that need further investigation. CONCLUSIONS: Based on this selective review, psychology professionals will be able to have rigorous, up-to-date information that allows them to make informed decisions when implementing empirically based psychotherapeutic procedures based on the characteristics of the people who require help.

Illness-related intrusive thoughts and illness anxiety disorder.

INTRODUCTION: Intrusive thoughts about health threats (illness-ITs) are a potential cognitive risk factor for the development and maintenance of illness anxiety disorder (IAD). This study analyzes the dimensionality of illness-ITs from normalcy to psychopathology, and it evaluates whether the appraisals instigated by the Its mediate between these thoughts and IAD symptoms. METHODS: Two groups of individuals participated in the study and completed the Illness Intrusive Thoughts Inventory and the Whiteley Index. The first group was composed of 446 non-clinical community participants. Of them, 264 individuals (68.6% women; Mage  = 30.03 [SD = 13.83]) reported having experienced an upsetting illness-IT in the past three months and were then included in the main analyses. The second group included 31 patients with a current main diagnosis of IAD based on DSM-5 criteria (51.6% women; Mage  = 32.74 [SD = 9.69]). Their severity was assessed with the Hypochondriasis Yale-Brown Obsessive-Compulsive Scale -Modified version, with scores ranging from 15 to 58 (M = 46.12, SD = 9.41). RESULTS: Illness-ITs are common in both non-clinical individuals and in patients with IAD, and they instigate dysfunctional emotional, cognitive, and behavioral consequences, although with greater intensity in patients than in non-clinical individuals. The relationship between illness-ITs and IAD is mediated by overestimation of threat and thought-action fusion-probability appraisals. CONCLUSION: Illness-ITs are a dimensional cognitive experience. The way they are appraised facilitates their escalation into symptoms of IAD. PRACTITIONER POINTS: Provides support for the cognitive explanatory model of IAD and its usefulness in clinical practice. Indicates that the way people interpret and react to naturally occurring intrusive thoughts about illness seems to be a vulnerability marker for developing an illness anxiety disorder. Emphasizes that the meaning that patients with IAD ascribe to their intrusive thoughts about illnesses must be a main target in the cognitive-behavioral treatment of IAD. Suggests that the importance of intrusive thoughts in IAD does not lie in the frequency with which they are experienced, but in the way, they are appraised/interpreted, which is what determines whether they become a clinically significant symptom. Indicates that the relationship between illness intrusive thoughts and IAD symptoms in non-clinical individuals is based on: overestimating the negative consequences of experiencing an illness intrusive thought; and the appraisal that having such a thought would increase its likelihood of coming true. Shows that the frequency of illness-related intrusive cognitions is associated with worse cognitive and behavioral consequences.

Dysfunctional beliefs as mediators between illness-related intrusive thoughts and health anxiety symptoms.

BACKGROUND: Cognitive behavioural models of hypochondriasis assume that dysfunctional illness-related beliefs are involved in the genesis and maintenance of the disorder. The role that other more general dysfunctional beliefs about thoughts play in this disorder has also been highlighted. Internal triggers such as illness-related intrusive thoughts could activate these beliefs. AIM: The present paper examines whether general dysfunctional beliefs about distressing thoughts, such as intolerance of uncertainty, over-estimation of threat, and thought-action fusion-likelihood, mediate between illness-related intrusive thoughts and health anxiety symptoms. METHOD: A group of participants composed of individuals with hypochondriasis (n = 31; 51.5% women; mean age = 32.74 years, SD = 9.96) and community individuals (n = 219; 54.3% women; mean age = 39.56 years, SD = 15.20) completed a series of questionnaires to assess illness-related intrusive thoughts (INPIE), dysfunctional beliefs about thoughts (OBSI-R), and health anxiety symptoms (SHAI). RESULTS: Results from a multiple parallel mediation analysis indicate that over-estimation of threat partially mediated the relationship between illness-related intrusive thoughts and health anxiety symptoms. CONCLUSIONS: The results support the importance of the tendency to over-estimate the threat in the relationship between intrusive thoughts related to illness contents and health anxiety. Conceptual and clinical implications of these results are discussed.

The Spanish validation of the Short Health Anxiety Inventory: Psychometric properties and clinical utility.

BACKGROUND/OBJECTIVE: The Short Health Anxiety Inventory (SHAI) is a widely used self-report instrument to evaluate health anxiety. To assess the SHAI's factor structure, psychometric properties, and accuracy in differentiating Spanish non-clinical individuals from patients with severe health anxiety or hypochondriasis. METHOD: A total of 342 community participants (61.6% women; M age = 34.60, SD = 14.91) and 31 hypochondriacal patients (51.6% women; M age = 32.74, SD = 9.69) completed the SHAI and other self-reports assessing symptoms of hypochondriasis, depression, anxiety sensitivity, worry, and obsessive-compulsive. RESULTS: The original two-factor structure was selected as the best structure, based on its parsimony and empirical support (Factor 1: Illness likelihood; Factor 2: Negative consequences of illness). Moreover, the Spanish version of the SHAI demonstrated good construct and concurrent and discriminant validity, and internal consistency. A cutoff of 40.5 (total score) accurately distinguished non-clinical individuals from patients with severe health anxiety or hypochondriasis. CONCLUSIONS: The SHAI is an adequate screening instrument to measure health anxiety in Spanish-speaking community adults.

INTRODUCCIÓN/OBJETIVO: El Inventario Breve de Ansiedad por la Salud (SHAI, por sus iniciales en inglés) es un autoinforme ampliamente empleado para evaluar ansiedad por la salud. El objetivo es evaluar la estructura factorial del SHAI, sus propiedades psicométricas, y exactitud diferenciando entre población española no clínica y pacientes con hipocondría. MÉTODO: Un total de 342 participantes extraídos de la población general (66% mujeres, M edad  = 35, DT = 14,91) y 31 pacientes con hipocondría (51,6% mujeres; M edad  = 32,74, DT = 9,69 completaron el SHAI y otros autoinformes de síntomas hipocondriacos, depresión, sensibilidad a la ansiedad, preocupaciones y obsesivo-compulsivos. RESULTADOS: La estructura de dos factores propuesta originalmente fue seleccionada como la mejor estructura debido a su parsimonia y soporte empírico (Factor 1: Probabilidad de enfermar; Factor 2: Consecuencias negativas enfermedad). La versión española del SHAI muestra una buena consistencia interna, y validez de constructo, concurrente y discriminante. El punto de corte de 40,5 (puntuación total) permite distinguir entre los individuos no clínicos y los pacientes con elevada ansiedad por la salud o hipocondría. CONCLUSIONES: El SHAI es un instrumento adecuado para la detección de ansiedad por la salud en población adulta hispano hablante.
