Seasonal Affective Disorder Test

People who notice recurring changes in mood, energy, sleep, appetite, motivation, or social engagement may use this questionnaire to organize what happens across darker and lighter months. As a seasonal affective disorder test, it helps the respondent consider whether these experiences form a meaningful pattern and how much they interfere with ordinary responsibilities. A seasonal depression test can support self-reflection when winter difficulties feel broader or more persistent than expected.

What This Assessment Explores

The questions examine seasonal changes in mood, energy, sleep, appetite, motivation, concentration, irritability, anxiety, social engagement, and interest. They also ask how these experiences affect work or study, communication, relationships, household responsibilities, self-care, and routines.

The result groups the responses into three dimensions:

• Functional Impact (0-20) measures disruption to daily functioning: Low impact 0-6, Moderate impact 7-13, High impact 14-20.
• Seasonal Pattern (0-20) measures how consistently symptoms worsen in fall or winter and improve in spring or summer: Low seasonal pattern 0-6, Moderate seasonal pattern 7-13, High seasonal pattern 14-20.
• Symptom Severity (0-30) measures the intensity of SAD-like symptoms during the recent seasonal period: Low 0-10, Moderate 11-20, High 21-30.

A seasonal mood assessment can help show whether the main concern is symptom intensity, disruption, seasonality, or a combination.

Methodology and Scientific Basis

Seasonality Assessment Form (Young et al., 2015) is the closest conceptual reference for this questionnaire’s focus on recurring seasonal symptoms. The seasonal syndrome described by Rosenthal et al. (1984) and the Seasonal Pattern Assessment Questionnaire discussed by Raheja et al. (1996) provide context. These sources support the construct being explored, not a claim that this online form reproduces or validates those instruments.

The items are self-report statements with four-option responses. Depending on wording, the respondent rates frequency, agreement, intensity, truthfulness, or how noticeable a seasonal change is. Responses are combined into the displayed scores; higher values indicate greater impairment, a clearer seasonal cycle, or more intense symptoms on the relevant dimension. The bands describe the displayed ranges rather than universal clinical cutoffs.

As a SAD symptom checker, the questionnaire depends on honest recall and may be influenced by stress, sleep problems, health conditions, or expectations about winter. Its profile is a structured prompt for examining patterns, not proof of a disorder, and this online form should not be assumed to share the published instruments’ norms, reliability, or validity.
