Hopkins Verbal Learning Test-Revised (HVLT-R)
Periodo de tiempo: baseline, weeks 2, 4, and 8
|
Hopkins Verbal Learning Test-Revised (HVLT-R) is a widely used neuropsychological assessment tool designed to evaluate verbal memory and cognitive function.
Developed by J. Brandt and Benedict in 2001, the HVLT-R consists of a list of 12 nouns divided into three semantic categories (e.g., dwelling places, four-legged animals, and precious stones), with four words per category.
The assessment involves three learning trials, where participants are presented with the list of words and are asked to recall as many words as possible immediately after each presentation.
Additionally, there is a delayed recall trial, where participants are asked to recall the words after a delay of 20-25 minutes.
The scoring principle is based on the number of correctly recalled words during each learning trial and the delayed recall trial.
The total score for the three learning trials and the delayed recall trial is calculated as well.

The Generalized Anxiety Disorder-7 is a standardized assessment tool developed by Spitzer et al. in 2006.
It is a 7-item questionnaire designed to evaluate the severity of anxiety symptoms over the past two weeks.
The scale covers various aspects of anxiety, including feelings of tension, worry, irritability, and difficulty relaxing.
Each item is rated on a 4-point scale, ranging from 0 (not at all) to 3 (nearly every day), with total scores ranging from 0 to 21.
Higher scores indicate more severe anxiety symptoms.
The GAD-7 is primarily used as a screening and assessment tool in clinical and research settings, aiding clinicians in identifying and quantifying anxiety symptoms, monitoring changes over time, and evaluating treatment effectiveness.
It is a simple, reliable, and valid instrument that can be easily administered and scored, making it a valuable addition to the clinical assessment of anxiety disorders.

Periodo de tiempo: baseline, weeks1, 2, 3, 4, and 8
|
The Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR-16), a rigorous and systematic self-assessment scale developed by Rush et al. in 2003 with subsequent refinements, is a widely recognized tool for quickly gauging depressive symptoms over the past week.
It comprises 16 items covering various dimensions of depression, including mood, sleep, appetite, energy levels, concentration, self-esteem, suicidal ideation, and daily functioning, each rated on a 4-point scale (0-3).
The scale assesses the severity and frequency of symptoms, with higher scores indicating more severe depression.
The QIDS-SR16 serves multiple purposes: it aids in screening and assessing depressive symptoms in clinical settings, allows individuals to monitor their depressive state over time, serves as a research tool in clinical studies evaluating treatment effectiveness, and provides valuable information that can support the diagnostic process when combined with clinical interviews.
