Description

The Short Mood and Feelings Questionnaire – Child Self-Report (SMFQ-C) is a widely used instrument designed to assess depressive symptoms in children and adolescents. It consists of 13 items, each scored on a three-point scale (0 = “Not True,” 1 = “Sometimes,” 2 = “True”). This self-report tool helps identify feelings of sadness, irritability, lack of energy, and other depressive symptoms experienced by the child or adolescent over the previous two weeks.

Analysis and Data Use

When analyzing data from the SMFQ-C, the following steps are typically involved:

Scoring: Each of the 13 items is scored based on the child’s responses. The total score ranges from 0 to 26, with higher scores indicating more severe depressive symptoms.

Interpretation:

Low Scores (0-5): Minimal or no depressive symptoms.

Moderate Scores (6-11): Mild depressive symptoms, may indicate a need for further monitoring.

High Scores (12 and above): Suggest significant depressive symptoms that may require clinical attention.

Statistical Analysis:

Descriptive Statistics: Mean, median, and standard deviation to understand the distribution of scores across a sample.

Reliability Analysis: Internal consistency is often tested using Cronbach’s alpha, with scores above 0.7 typically indicating good reliability.

Factor Analysis: To explore the underlying structure of the questionnaire and whether it measures a single construct (depression).

Correlation Analysis: To examine relationships between SMFQ-C scores and other variables, such as age, gender, and other mental health measures.

Cutoff Analysis: Researchers may calibrate cutoff scores to classify depressive symptom severity for specific populations.

Purpose

The SMFQ-C is used to:

Screen for depression in clinical and educational settings.

Identify children and adolescents who may require further mental health evaluation.

Monitor depressive symptom changes over time, especially before and after interventions (e.g., therapy).

Research the prevalence of depression and its predictors in various populations.

Calibration

For clinical or research use, it is essential to validate the SMFQ-C for the target population. This involves:

Norming the questionnaire with a representative sample to establish appropriate cutoff scores.

Cross-validation to ensure the tool is reliable across different subgroups (e.g., by age, gender, or cultural background).

Comparison with Clinical Diagnoses: Sensitivity and specificity analysis to determine how well the SMFQ-C predicts clinical depression diagnoses (e.g., using tools like the Children’s Depression Inventory or structured clinical interviews).
