Treating Emotional Disorders in Primary Care With Psychological Techniques (PsychPC)
A Pilot Study to Treat Emotional Disorders in Primary Care With Evidence-based Psychological Techniques: A Randomized Controlled Trial
The strong demand for primary care (PC) services in Spain exceeds resources. Part of this demand is due to the increasing number of anxiety, depression, and somatization disorders that affect the general population. These disorders, commonly known as emotional disorders, are very common in Spanish PC settings, they are poorly detected by physicians, rarely receive adequate treatment (if they receive treatment it is mostly drugs instead of psychological treatment), they generate a highly frequent use of PC services, a greater burden than physical diseases and tend to become chronic without treatment.
Other countries have successfully put psychological techniques in PC into practice (in the United Kingdom the program known as "Improving Access to Psychological Therapies" has obtained very positive results) in order to correctly diagnose and treat emotional disorders. The results obtained in terms of symptoms, quality of life, diagnosis, etc., have been better than the usual treatment offered in PC services, involving no side effects, fewer relapses, and lower costs in the long term.
The general aim of this study is to test how well a psychological treatment program for anxiety, depression, and somatization disorders works in PC and to compare the results obtained after seven 90-minute group sessions (every to two to four weeks approximately, for a period of 24 weeks) with the usual treatment offered in Spanish PC services. Similar results to the ones already obtained in other countries are expected to be found.
Approximately 1130 adults, regardless of their age and sex, with an anxiety, depression and/or somatization disorder (diagnosed with a simple and short questionnaire) will participate in this study.
Participation will be voluntary and confidentiality will be guaranteed. Half of the participants in the study will be randomly assigned to receive their usual care and the other half will receive psychological treatment, within the same health care centre. Since it is a "double-blind" study, neither the health professional nor the patient will know which treatment will be applied. Psychological assessments will be carried out before and after receiving treatment and participants will be followed up at 3, 6 and 12 months.
Participation will pose no risks different from the typically present when receiving usual treatment. The aim of this study will be to maximize benefits and reduce potential harms (principle of proportionality).

Intervention / Treatment
Detailed Description
Secondary objectives:
- The experimental in comparison with the control group will report a greater decrease (including pre-post-treatment differences and follow-up at 3, 6 and 12 months) in emotional symptoms (total scores of anxiety, depressive and somatic symptoms as measured by the Patient Health Questionnaire), cognitive factors, and percentage of cases with probable emotional disorders (anxiety, depression, and somatization disorders).
- The experimental in comparison with the control group will report a decrease in its levels of work, family and social impairment (Sheehan Disability Scale), and an increase in its levels of physical health, psychological, social, and environmental quality of life (as measured by the different World Health Organization Quality of Life; WHOQOL-BREF scales).
- The experimental group in comparison with the control group will reduce the frequency of Primary Care visits (as well as other health care costs) at 6 month follow-up.
- In addition, the experimental group will report higher treatment satisfaction than the control group.
The following variables will be assessed:
- Clinical symptoms (anxiety, depression, somatizations), levels of adjustment (work, family, social),
- Quality of life (physical health, psychological, social, environmental),
- Emotional symptoms and thoughts (worries, beliefs, coping strategies, negative thoughts, etc.),
- Treatment satisfaction
- Frequent use of services
- Psychoactive drug use.
Patient recruitment
Inclusion criteria:
• Any adult patient seeking Primary Care treatment at any of the selected sites in Spain with a probable anxiety, mood and/or somatisation disorder (diagnosed with the Patient Health Questionnaire; PHQ-9) may voluntarily participate in the study regardless of his/her age and sex.
Exclusion criteria:
- Patients with severe mental disorders (e.g., bipolar disorder, personality disorder)
- Patients with a history of frequent or recent suicide attempt(s)
- Patients with a high level of disability (as measured by the Sheehan Disability Scale) who seek Primary Care treatment.
- Patients with severe anxiety disorders (e.g., comorbid substance use disorders) and severe mood disorders (Patient Health Questionnaire; PHQ-9 total score >= 20).
- Patients who do not meet diagnostic criteria for a probable emotional disorder or do not reach the established Patient Health Questionnaire cut-off points.
The minimum sample size required to obtain a significant result has been calculated with the Sample-Power SPSS program. The study should include 563 patients in each condition, with a total of 1126 patients, accounting for a 20% attrition or dropout. With this sample size, the result will be statistically significant (85% statistical power) when comparing both groups, even if they differ by one point only, with a standard deviation of 5, a range of scores from 0-27 for the PHQ-9, and it will enable us to conclude that the result is different for each group with a 95% confidence level.
Both groups will be equivalent in all measures before receiving treatment. 2x2 within and between-groups analyses of variance (group x treatment) will be conducted for each dependent variable. The effect size for each dependent variable will be calculated in both groups, as well as the 95% confidence interval, taking into account the number of treatment sessions. Primary analyses will follow the "intention-to-treat" principle in such a way that all individuals who participate in the study will be considered as members of one group even if they have not yet completed the protocol. "Therapeutic success" will be obtained if the average scores of the experimental group are significantly lower than those of the control group in the dependent variables (anxiety, depression, and somatization symptoms), and when the effect sizes are medium to large and significantly higher than those of the control group (especially in the case of anxiety symptoms). In addition, the results obtained by each group in terms of degree of disability (work, family and social), quality of life, treatment satisfaction, costs and cost-efficiency of both treatments will be compared.
It will be carried out in twenty five Primary Care (PC) centres in Madrid, Valencia, Albacete, Mallorca, Murcia, Vizcaya, Cordoba, Galicia, and Cantabria, and may be extended to other centres and cities.
It is expected to start in September 2013 and posttreatment will end by December 2018. The study will be open to participants until recruitment is completed. The follow-up period will end by September 2019.
