Purpose of the Questionnaire (Scale)

The Hinting Task was developed by Corcoran, Mercer, and Frith in 1995 with the primary aim of assessing the ability to understand indirect intentions and social hints. This tool is a critical instrument for evaluating social cognitive functioning, with particular application to populations with psychopathological disorders, mainly schizophrenia. Its basic use is in both clinical and research practice, where it is employed to assess Theory of Mind (ToM).

Questionnaire (Scale) Structure

The task consists of 10 short dialogues, in each of which one character makes a hint. The participant is asked to recognize and interpret the implied meaning of these hints. The administration procedure is relatively simple and does not require specialized equipment, with an average completion time of 15–20 minutes. Its clear structure and ease of use make the tool ideal for broad clinical and research applications.

Scoring of Questions

The scoring system of the task is three-tiered. Specifically:
2 points are awarded when the participant provides the correct answer without the need for a prompt,
1 point when the correct answer is given after a prompt,
0 points if the participant fails to understand the hint.
The total score ranges from 0 to 20 points, with higher scores indicating better performance in understanding social hints.

Statistical Analysis

The statistical analysis of the task results allows for the quantitative assessment of the ability to understand hints. The maximum possible score is 20 points, while scores below 10 usually indicate difficulties in comprehending hints. Among healthy adults, mean scores typically range between 16–18 points, whereas individuals with schizophrenia usually score significantly lower, typically in the range of 8–12 points.

Validity of the Questionnaire (Scale)

The validity of the task has been confirmed in numerous studies. The tool demonstrates high discriminative ability between clinical and non-clinical populations, as well as good convergent validity with other Theory of Mind measures. Moreover, the task has been validated in various cultural and linguistic groups. In the Greek population, its validity has been confirmed, although the use of locally validated versions is recommended for greater accuracy.

Reliability of the Questionnaire (Scale)

Regarding reliability, the task demonstrates high internal consistency, with Cronbach’s α coefficients ranging between 0.75–0.85. Its test-retest reliability is equally satisfactory, with indices above 0.70. The tool is distinguished for the stability of its measurements and its ability to effectively discriminate between different diagnostic groups.
