What is the CogniFit Depression Test?

What is the CogniFit Depression Test?

  • Evaluate the risk index for the presence of depression
  • For adults and seniors
  • Takes about 30-40 minutes to complete
  • Reliability analysis of the evaluation - Only in English Download

The Cognitive Assessment for Depression Patients (CAB-DP) from CogniFit is a professional test that uses clinical questions and tasks to quickly and accurately detect the presence of symptoms and altered cognitive processes affected by depression, which is one of the most common mood disorders.

This innovative and reliable depression test is a resource that makes it possible to take a complete cognitive screening and understand the user's cognitive strengths and weaknesses, as well as detect their risk index for depression. This psychometric test is designed for user's 16 and older, adults, and seniors that are at risk for depression.

The cognitive assessment will automatically generate a detailed cognitive report. The depression test usually takes about 30-40 minutes to complete.

A depression diagnosis requires a multi-disciplinary and exhaustive differential diagnosis in order to discard symptomology that may be better described by another mood disorder or disease.

Clinical consultations, questionnaires, and clinical evaluation scales are the most effective tools to diagnose depression, but they may not be enough to determine its degree. In order to better understand the severity of the alteration, an exhaustive assessment of mood disorders is necessary. Note that CogniFit does not directly offer a medical diagnosis for depression. We recommend using this online depression test to complement a professional diagnosis, and never as a replacement for a clinical consultation.

Emotional symptoms

Sadness, lack of interest, or hopelessness are some of the main emotional symptoms in depressive disorders. Dopamine and serotonin are the main neurotransmitters responsible for regulating emotional state. Different studies have shown that a reduced dopaminergic and serotonergic activity may be related to depression, causing depressive symptoms like sadness or apathy.

Physical symptoms

Depressive disorders are related to a chemical imbalance of neurotransmitters. Some physical sensations may manifest during depression, like fatigue, headache, muscle pain, loss of appetite, or sleep problems. If you detect any of these problems, you may want to take the depression test (CAB-DP).

Cognitive symptoms

Depression is related to a series of cognitive deficits that, apart from negatively affecting the person's daily life, contributes to a magnified or prolonged duration of this mood disorder. Scientific literature consistently shows that people with depression have more trouble with attention and cognitive flexibility, along with other abilities.

Associated symptoms

A series of associated symptoms, like irritability, crying, substance abuse, or weight changes are common in depressive disorders. These associated symptoms are important in detecting depression, and are related to some of the symptoms that we mentioned before.

Description of the diagnostic criteria questionnaire

Description of the diagnostic criteria questionnaire

Depression is characterized by a series of clinical signs and symptoms. These indicators can help you understand whether or not someone may have this mood disorder. This is why the first step of the depression assessment is a questionnaire to detect the main diagnostic criteria and symptoms of depression for each age range.

The questions presented in the questionnaire are similar to those that may be found in a diagnostic manual, clinical questionnaire, or scales for depression. However, they have been simplified in order to be easily understood by almost any user.

Diagnostic criteria of depression for adults and seniors

Made of a series of easy-to-answer questions that should be completed by the professional in charge or by the person taking the assessment. The questionnaire collects information from the following areas: Emotional symptoms (sadness, guilt, hopelessness, etc.), Physical symptoms (fatigue, muscle pain, sleep problems, etc.), and Associated symptoms (irritability, weight change, substance abuse, etc.).

What cognitive skills are assessed with this Depression test?

What cognitive skills are assessed with this Depression test?

The presence of alterations in some cognitive skills may be an indicator of depression. A general profile of the cognitive skills may indicate how severe the cognitive alteration cause by the disorder is.

Divided Attention

Divided attention can be defined as the ability of our brain to attend to different stimuli or tasks at the same time, and thus, respond to the multiple demands of the environment. Divided attention not only appears to be related to depression, but also appears to be a good predictor of response to treatment, remission of symptoms, and risk of relapse. The deterioration of divided attention capacity can be explained either by the reduction of attention resources or by the deterioration of activation and/or declining control of attention resources by the central executive.

Our Digital Cognitive Assessments

CogniFit digital tests are designed to measure a specific areas of cognition and are grouped together to form customized batteries based on the unique requirements of the study design and population. Learn more about our different tests and how they can support the unique needs of your study by exploring the details and demos below.

Tapping Test

The Speed Test REST-HECOOR exercise was inspired by the classic test of Fingertip tapping from the assessment battery NEPSY (Korkman et al., 1998). The test-taker is required to keep on clicking for 10 seconds and as rapidly as possible with the mouse, or finger if using a touch-screen device, in a defined area on the screen. Data is collected as the number of clicks during the allocated time, number of clicks inside the defined area and number of clicks outside it.

Psychomotor Vigilance Test

The Resolution Test REST-SPER was inspired by the classic paradigms Go/No Go Task (Gordon & Caramazza, 1982), Continuous Performance Test (Conners, 1989; Epstein et al., 2001), and the Psychomotor Vigilance Task (Dinges & Powell, 1985). The test-taker is required to rapidly press on circles which appear on the screen and to ignore hexagons should they also appear. Embedded in the task are 16 circles-only items and 8 circles-and-hexagons items. For each item data is collected on response time, response accuracy and cursor distance from target center.

Visual Working Memory Span Test

The Concentration Test VISMEM-PLAN took as a reference the Corsi block-tapping test (Corsi, 1972; Kessels et al., 2000; Wechsler, 1945). In the first part of the task, some circles, within a fixed array of circles, light up. The test-taker is required to memorize which circles, within the array, have lit up and then try to reproduce the sequence in the right order. In the second part of the task, a delay of 4 secs is added between the first screen and the playback screen, in order to increase the time the user must retain the information.

Eye-Hand Coordination Test Fixed Trajectory and Predictable Direction

The Synchronization Test UPDA-SHIF is based on the Vienna Test System (VST) (Whiteside, 2002). In this task the test-taker is required to carefully and precisely track a ball which moves along a path. The distance in pixels between the center of the ball and the cursor moved by the user is considered to calculate the accuracy score.

Multimodal Lexical Memory Test

The Identification Test COM-NAM is based on the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). For each object shown, the test-taker must choose from three possibilities: 1) the item is presented for the first time in the task or 2) the last time it appeared the item was spoken or 3) the last time it appeared the item was presented as a picture.

Digit Span Test

The Sequencing Test WOM-ASM is based on the classic direct and indirect digit test of the WAIS-III (Wechsler, 1997). The test-taker is required to remember and reproduce increasingly longer number sequences, which appear, each in its turn, on the screen. The task will begin with a two- -number sequence.

Lexical Memory Test

The Inquiry Test REST-COM took as a reference the classic Boston Naming Test (Kaplan et al., 1983), the vocabulary test from WAIS-III (Wechsler, 1997), the Test of Variables of Attention (Greenberg et al., 1996), and the Rey Auditory Verbal Learning Test (Schmidt, 1994). A series of objects are shown. In a new series of objects, the test-taker must then recognize only those objects that were previously displayed. This new series could be presented as images or as spoken words.

Stroop Test

The Equivalencies Test INH-REST was based on the classic Stroop test (Stroop, 1935). The test-taker is asked to press on the spacebar (go action) only if the color names on the screen are printed in the matching color and to refrain from pressing (no-go) if the color of the letters does not match the printed color name.

Divided Attention Test

The Simultaneity Test DIAT-SHIF stems from the classic Stroop test (Stroop, 1935), the Vienna Test System (Whiteside, 2002), and the Test of Variables of Attention (Greenberg et al., 1996). The test-taker is required to accurately follow a ball moving and turning in all directions on the screen while, at the same time, performing a variant of the Stroop test.

Depression and the Brain

Depression and the Brain

Emotional, behavioral, and cognitive problems related to depression are caused by various brain alterations. The main areas affected by depression are the limbic system and the prefrontal cortex, which are closely related to each other.

1 Limbic System

The limbic system is made up of a set of brain structures in charge, in large part, of identifying and controlling emotions. The structures in the limbic system that seem to be altered by depression are the hippocampus, the amygdala, the basal ganglia, and cingulate cortex, and the hypothalamus. Some studies have shown that people with depression have a reduced volume in the hippocampus, which may explain some of the cognitive problems associated with this disorder.

2 Prefrontal Cortex

The prefrontal cortex is in the frontmost part of the brain and is in charge of superior functions, like planning and other executive functions. It's been shown that there is a significant affectation in the dorsolateral prefrontal cortex and in the orbitofrontal prefrontal cortex. The dorsolateral cortex is related to initiative, fluidity, inhibition, shifting, self-regulation, planning, and decision making, all of which are skills that are often altered in people with depression. The orbitofrontal cortex, which is mainly related to social behavior and personality, is also often reduced in volume in people with depression.

3 Locus Coeruleus

Low Noradrenaline: Depression causes this neurotransmitter to decrease, which is closely related to initiative, fluidity, inhibition, cognitive shifting, self-control, planning, decision making, and attention, which are skills commonly altered in Depression.

4 Raphe Nuclei

Decrease in Serotonin: Serotonin plays an important role in positive or negative moods. When serotonin levels are low, so are feelings of happiness. It is also related to digestion, body temperature, and sleep.

5 Hippocampus

The hippocampus is the cerebral epicenter of memory. It has been shown that patients who have had depression for years had a smaller and narrower hippocampus, which largely affects all of the cognitive abilities related to memory.
