BACKGROUND: Major depression will become the second most important cause of disability in 2020. Computerised cognitive-behaviour therapy could be an efficacious and cost-effective option for its treatment. No studies on cost-effectiveness of low intensity vs self-guided psychotherapy have been carried out.
AIM: To assess the efficacy of low intensity vs self-guided psychotherapy for major depression in the Spanish health system.
METHODS: The study is made up of 3 phases: 1.- Development of a computerised cognitive-behaviour therapy for depression tailored to Spanish health system. 2.- Multicenter controlled, randomized study: A sample (N=450 patients) with mild/moderate depression recruited in primary care. They should have internet availability at home, not receive any previous psychological treatment, and not suffer from any other severe somatic or psychological disorder. They will be allocated to one of 3 treatments: a) Low intensity Internet-delivered psychotherapy + improved treatment as usual (ITAU) by GP, b) Self-guided Internet-delivered psychotherapy + ITAU or c) ITAU. Patients will be diagnosed with MINI psychiatric interview. Main outcome variable will be Beck Depression Inventory. It will be also administered EuroQol 5D (quality of life) and Client Service Receipt Inventory (consume of health and social services). Patients will be assessed at baseline, 3 and 12 months. An intention to treat and a per protocol analysis will be performed.

| Severity of depressive symptomatology measured by Beck Depression Inventory II | This is one of the most widely questionnaires used to evaluate severity of depression in pharmacological and psychotherapy trials. This questionnaire has been used because it is recommended to assess depression in primary care patients in which comorbidity with medical disorders is frequent. The Spanish validated version of the questionnaire will be used. | At baseline |

| Mini-International Neuropsychiatric Interview (MINI). | This is a short structured diagnostic psychiatric interview that yields key DSM-IV and ICD-10 diagnoses. MINI can be administered in a short period of time and clinical interviewers need only a brief training. The MINI has been translated and validated in Spanish. | At Baseline |
| EuroQoL-5D questionnaire (EQ-5D - Spanish version) | Generic instrument of health-related quality of life. It has two parts: part 1 records self-reported problems in each of five domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each domain is divided into three levels of severity corresponding to no problems, some problems, and extreme problems. Values range from 1 (best health state) to 0 (death). Part 2 records the subject's self-assessed health on a VAS, a 10 cm vertical line on which the best and worst imaginable health states score 100 and 0, respectively. | At Baseline |
| Client Service Receipt Inventory - adapted (CSRI - Spanish version) | Questionnaire for collecting information about use of healthcare and social care services and other economic impacts (such as time off work due to illness). The variant used in this study was designed to collect retrospective data on service utilization during the previous months after the last assessment. Data on baseline assess the previous three months before inclusion. | At baseline |
| Overall Depression Severity and Impairment Scale | OASIS consists of 5 items that measure the frequency and severity of anxiety, as well as level of avoidance, work/ school/home interference, and social interference associated with anxiety. The instructions orient the respondent to considerate wide range of anxiety symptoms (e.g., panic attacks, worries, flashbacks) when answering the questions, and the time frame is "over the past week". Respondents select among five different response options for each item, which are coded 0-4 and summed to obtain a total score. | At baseline |
| Positive and Negative Affect Scale (PANAS) | PANAS consists of 20 items that evaluate two independent dimensions: positive affect (PA) and negative affect (NA). The range for each scale (10 items on each) is 10 to 50. The instrument's psychometric properties are quite satisfactory. It has a validated Spanish version. | At Baseline |
| Credibility/expectancy questionnaire | It is a quick and easy-to-administer scale for assessing treatment expectancy and rationale credibility. Credibility has been defined as how believable, convincing, and logical the treatment is, whereas expectancy refers to improvements that clients believe will be achieved. The aspects that address these two scales relate to: 1) treatment rationale, 2) treatment satisfaction, 3) degree to which I would recommend to a friend who had the same problem, 4) extent to which is considered to be useful in the same case, 6) extent to which the intervention would be considered aversive. | At Baseline |
