          Abstract

          Empirically supported psychological therapies have been developed for many mental health conditions. However, in most countries only a small proportion of the public benefit from these advances. The English Improving Access to Psychological Therapies (IAPT) program aims to bridge the gap between research and practice by training over 10,500 new psychological therapists in empirically supported treatments and deploying them in new services for the treatment of depression and anxiety disorders. Currently IAPT treats over 560,000 patients per year, obtains clinical outcome data on 98.5% of these individuals and places this information in the public domain. Around 50% of patients treated in IAPT services recover and two-thirds show worthwhile benefits. The clinical and economic arguments on which IAPT is based are presented, along with details of the service model, how the program was implemented, and recent findings about service organization. Limitations and future directions are outlined.

          The Health Anxiety Inventory: development and validation of scales for the measurement of health anxiety and hypochondriasis.

          A self-rated measure of health anxiety should be sensitive across the full range of intensity (from mild concern to frank hypochondriasis) and should differentiate people suffering from health anxiety from those who have actual physical illness but who are not excessively concerned about their health. It should also encompass the full range of clinical symptoms characteristic of clinical hypochondriasis. The development and validation of such a scale is described. Three studies were conducted. First, the questionnaire was validated by comparing the responses of patients suffering from hypochondriasis with those suffering from hypochondriasis and panic disorder, panic disorder, social phobia and non-patient controls. Secondly, a state version of the questionnaire was administered to patients undergoing cognitive-behavioural treatment or wait-list in order to examine the measure's sensitivity to change. In the third study, a shortened version was developed and validated in similar types of sample, and in a range of samples of people seeking medical help for physical illness. The scale was found to be reliable and to have a high internal consistency. Hypochondriacal patients scored significantly higher than anxiety disorder patients, including both social phobic patients and panic disorder patients as well as normal controls. In the second study, a 'state' version of the scale was found to be sensitive to treatment effects, and to correlate very highly with a clinician rating based on an interview of present clinical state. A development and refinement of the scale (intended to reflect more fully the range of symptoms of and reactions to hypochondriasis) was found to be reliable and valid. A very short (14 item) version of the scale was found to have comparable properties to the full length scale. The HAI is a reliable and valid measure of health anxiety. It is likely to be useful as a brief screening instrument, as there is a short form which correlates highly with the longer version.

            Patient preference for psychological vs pharmacologic treatment of psychiatric disorders: a meta-analytic review.

            Evidence-based practice involves the consideration of efficacy and effectiveness, clinical expertise, and patient preference in treatment selection. However, patient preference for psychiatric treatment has been understudied. The aim of this meta-analytic review was to provide an estimate of the proportion of patients preferring psychological treatment relative to medication for psychiatric disorders. A literature search was conducted using PubMed, PsycINFO, and the Cochrane Collaboration library through August 2011 for studies written in English that assessed adult patient preferences for the treatment of psychiatric disorders. The following search terms and subject headings were used in combination: patient preference, consumer preference, therapeutics, psychotherapy, drug therapy, mental disorders, depression, anxiety, insomnia, bipolar disorder, schizophrenia, substance-related disorder, eating disorder, and personality disorder. In addition, the reference sections of identified articles were examined to locate any additional articles not captured by this search. Studies that assessed preferred type of treatment and included at least 1 psychological treatment and 1 pharmacologic treatment were included. Of the 644 articles identified, 34 met criteria for inclusion. Authors extracted relevant data including the proportion of participants reporting preference for psychological or pharmacologic treatment. The proportion of adult patients preferring psychological treatment was 0.75 (95% CI, 0.69-0.80), which was significantly higher than equivalent preference (ie, higher than 0.50; P < .001). Sensitivity analyses suggested that younger patients (P = .05) and women (P < .01) were significantly more likely to choose psychological treatment. A preference for psychological treatment was consistently evident in both treatment-seeking and unselected (ie, non-treatment-seeking) samples (P < .001 for both) but was somewhat stronger for unselected samples. Aggregation of patient preferences across diverse settings yielded a significant 3-fold preference for psychological treatment. Given evidence for enhanced outcomes among those receiving their preferred psychiatric treatment and the trends for decreasing utilization of psychotherapy, strategies to maximize the linkage of patients to preferred care are needed. © Copyright 2013 Physicians Postgraduate Press, Inc.

              Psychometric properties of the Social Phobia Inventory (SPIN): New self-rating scale

              Of available self-rated social phobia scales, none assesses the spectrum of fear, avoidance, and physiological symptoms, all of which are clinically important. Because of this limitation, we developed the Social Phobia Inventory (SPIN). To establish psychometric validation of the SPIN. Subjects from three clinical trials and two control groups were given the 17-item, self-rated SPIN. Validity was assessed against several established measures of social anxiety, global assessments of severity and improvement, and scales assessing physical health and disability. Good test – retest reliability, internal consistency, convergent and divergent validity were obtained. A SPIN score of 19 distinguished between social phobia subjects and controls. The SPIN was responsive to change in symptoms over time and reflected different responses to active drugs v. placebo. Factorial analysis identified five factors. The SPIN demonstrates solid psychometric properties and shows promise as a measurement for the screening of, and treatment response to, social phobia.
