- Brief Summary
The purpose of this study is to investigate the feasibility, acceptability and preliminary efficacy of an internet delivered cognitive behavior treatment (ICBT) for people with prolonged grief disorder (PGD) compared to a face-to-face intervention for PGD.
- Detailed Description
Grief is an intense emotional reaction to the loss of a loved one. It produces feelings of regret and longing that usually decrease over time. However, some people have difficulty adapting to the loss and develop Prolonged Grief Disorder (PGD). An open clinical trial will be conducted to investigate the feasibility \[initial efficacy and acceptability\] of an Internet delivered cognitive behavior treatment (ICBT) for adult people diagnosed with prolonged grief disorder (PGD). There will be at least 24 participants that will be randomly assigned to experimental group (internet-based treatment for PGD) or active control group (traditional face- to-face intervention for PGD). Four assessment moments will be included (pre-treatment, post-treatment, 3 months follow-up and 12 months follow-up). The present study aims to improve knowledge about the feasibility, acceptability and preliminary efficacy of an ICBT for PGD and conduct a preliminary comparison between two intervention conditions (internet-based intervention vs. traditional face-to-face intervention). Also, the investigators aim to collect information that can help to improve the efficacy and acceptability of Internet-based interventions in general.

Good psychometric properties; cronbach's alpha of0.94 in the original version and 0.88 in the Spanish adaptation.
It consists of 19 items with five response categories (Likert): 0; never 1; rarely 2; sometimes 3; often and 4; forever. The items value the frequency of the symptom explored (emotional, cognitive or behavioral). It is completed in approximately 10 minutes.
The total score is calculated by adding the score of the 19 items. The total score ranges from 0 to 76, with highest scores corresponding to a greater probability of suffering complicated grief.Change in the Beck Depression Inventory - Second Edition validated in the Spanish population immediately pre-treatment, immediately post-treatment, 3-month post-treatment, 12-month post-treatment It is a self-applied instrument that assesses characteristic attitudes and symptoms of depression. Psychometric properties; Cronbach's alpha of 0.76 to 0.95 and test-retest reliability of around 0.8. It consists of 21 items that are scored on a scale from 0 to 3. It is calculated by adding the score of the 21 items and the maximum total score is 63.
- Secondary Outcome Measures

It also measures the level of avoidance, work, academic, and home interference, and social interference associated with depression. Psychometric properties; Cronbach's alpha of 0.91 to 0.94 in the original version and good convergent and discriminant validity.
Cronbach's alpha of 0.93 in the Spanish adaptation and excellent convergent and discriminant validity. It consists of 5 items that are scored on a scale of 0 to 4. It is calculated by adding the score of the 5 items and the maximum score is 20.Change in the Work and Social Adjustment Scale (WSAS) validated in Spanish language immediately pre-treatment, immediately post-treatment, 3-month post-treatment, 12-month post-treatment It is a self-applied instrument to assess psychosocial functional impairment. Psychometric properties; good to excellent test-retest reliability, sensitivity to change and internal consistency (α = 0.70 to 0.94) in the original version. Good concurrent validity and excellent internal consistency in the Spanish version. It consists of 5 items that are scored on a scale of 0 (not at all) to 8 (very severely). It is calculated adding the score of all the items and the maximum total score is 40. Higher scores indicate greater interference in different areas.
Change in the Positive and Negative Affect Schedule (PANAS) validated in the Spanish population immediately pre-treatment, weekly during treatment, immediately post-treatment, 3-month post-treatment, 12-month post-treatment It is a self-applied instrument to assess two independent dimensions of affectivity: Positive Affect (PA) and Negative Affect (NA). Psychometric properties; excellent internal consistency in the original version (α = 0.84 to 0.90) and convergent and discriminant validity. Excellent internal consistency in the Spanish adaptation (α =0.87 to 0.91). It consists of 20 items that are scored on a 1-5 scale. It has two subscales: positive affect (10 items) and negative affect (10 items). It is calculated by adding each of the items on the two scales separately. The maximum score is 50 for each of the subscales.
Change in Purpose-In-Life Test (PIL- 10) immediately pre-treatment, immediately post-treatment, 3-month post-treatment, 12-month post-treatment It is a short form of the 20-items Purpose-In-Life Test (Crumbaugh, 1968).
