How this service works
Sheikh 1986 GDS-15: fifteen yes/no items as asked. Reverse-scored (false=1): satisfied_with_life, good_spirits, happy_most_of_time, wonderful_to_be_alive, full_of_energy; other ten score 1 if true. Sum 0-15. No later 0-4/5-9/10+ cutoffs. Not a diagnosis, not PHQ-9, not the 30-item GDS, not a medical device. magent does not interview.
Output
Returns a single integer total score from 0 to 15 representing the sum of depression-direction responses, with five positive items reverse-scored (false=1) and ten negative items scored when true=1, per the Sheikh 1986 GDS-15 algorithm.
Example use cases
Geriatric clinic intake screening
“I just administered the 15-item geriatric depression scale to a patient and recorded their answers: satisfied_with_life=false, dropped_activities=true, life_empty=true, often_bored=true, good_spirits=false, afraid_something_bad=true, happy_most_of_time=false, often_helpless=true, prefer_stay_home=true, more_memory_problems=true, wonderful_to_be_alive=false, pretty_worthless=true, full_of_energy=false, situation_hopeless=true, most_people_better_off=true — what is their GDS-15 total score?”
EHR workflow automated scoring
“For my automated chart documentation, compute the GDS-15 score using these responses: satisfied_with_life=true, dropped_activities=false, life_empty=false, often_bored=false, good_spirits=true, afraid_something_bad=false, happy_most_of_time=true, often_helpless=false, prefer_stay_home=false, more_memory_problems=false, wonderful_to_be_alive=true, pretty_worthless=false, full_of_energy=true, situation_hopeless=false, most_people_better_off=false.”
Research study data scoring
“I'm processing survey responses for a study and need the GDS-15 score for a participant who answered: satisfied_with_life=false, dropped_activities=true, life_empty=false, often_bored=true, good_spirits=false, afraid_something_bad=false, happy_most_of_time=false, often_helpless=false, prefer_stay_home=true, more_memory_problems=true, wonderful_to_be_alive=false, pretty_worthless=false, full_of_energy=false, situation_hopeless=false, most_people_better_off=true.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/gds_15When to prefer
Use this endpoint when you need the validated Sheikh 1986 GDS-15 short-form geriatric depression score and already have all 15 yes/no item responses collected externally. It is not a substitute for PHQ-9 scoring, the 30-item GDS, or any diagnostic tool — it only computes the arithmetic total with correct reverse-scoring.
Side effects
- Missing any of the 15 required boolean query parameters returns a validation error
- Passing non-boolean values for item parameters causes a schema error
- Network or payment failure (x402) prevents scoring
