The Clinical Threshold
In 2022, a peer-reviewed clinical investigation administered the PHQ-9, GAD-7, and PSS-10 to 250 coaching students in Kota. One in three met the diagnostic criteria for clinical depression. This is how the clinical team measured the psychological toll of competitive preparation.
When the Tata Institute of Social Sciences (TISS) published its 2018 report showing that 32% of Kota students exhibited depression symptoms, some industry representatives questioned the findings. The report was an administrative commission by a state government, they argued, conducted by sociologists rather than medical clinicians, and not subjected to the blind peer review of a medical journal.
Four years later, in 2022, a clinical research team led by Dr. B. Parihar and affiliated with the Department of Community Medicine in Kota published an independent investigation in the *Journal of Family Medicine and Primary Care*.
Their methodology was rigorous: standardized clinical psychometric instruments (PHQ-9, GAD-7, PSS-10), face-to-face physician oversight, stratified hostel sampling, and full statistical verification.
The result did not contradict the earlier government report. It validated it with clinical precision.
The study found that 33.6% of enrolled coaching students met the established medical cutoff for moderate-to-severe clinical depression. Over 40% registered clinical anxiety. More than 70% reported chronic sleep restriction under six hours a night.
This article examines what Parihar et al. measured, how they calibrated their clinical thresholds, why sleep deprivation acts as a neurobiological multiplier in coaching hostels, and what peer-reviewed medical literature confirms about student mental health in India’s entrance examination capital.
PHQ-9 Depression Severity Breakdown in Kota Coaching Students (N=250)
Proportion of students across clinical severity classifications (Parihar et al., 2022)
Within normal healthy threshold
Sub-clinical emotional distress
Clinical threshold crossed — evaluation indicated
Substantial psychiatric impairment
Critical psychiatric intervention required
Data from Parihar et al., Journal of Family Medicine and Primary Care (2022). PHQ-9 scores ≥ 10 indicate clinical depressive disorder requiring professional follow-up.
The clinical method: How the study was conducted
Unlike informal opinion polls or general social surveys, clinical cross-sectional studies follow strict epidemiologic criteria.
The research team established a stratified sample across three primary coaching clusters in Kota: Vigyan Nagar, Talwandi, and Mahaveer Nagar. These neighborhoods house the densest concentration of student hostels, private paying-guest (PG) lodgings, and coaching campuses.
A total of 250 students agreed to participate after receiving formal informed consent, with confidentiality strictly guaranteed to eliminate fear of institutional retribution.
The researchers deployed three widely cited psychometric batteries: 1. PHQ-9 (Patient Health Questionnaire): A 9-question instrument mapping directly onto the DSM-IV and DSM-5 diagnostic criteria for Major Depressive Disorder (MDD). Scores from 0–4 denote minimal depression, 5–9 mild, 10–14 moderate, 15–19 moderately severe, and 20–27 severe. A score of 10 or greater serves as the universally accepted clinical benchmark indicating the need for immediate therapeutic or pharmacological evaluation. 2. GAD-7 (Generalised Anxiety Disorder-7): A 7-item scale measuring uncontrollable worry, restlessness, muscle tension, and dread. Scores of 10 and above identify moderate-to-severe anxiety disorders. 3. PSS-10 (Perceived Stress Scale): Developed by Cohen et al., measuring the degree to which life situations over the previous month were appraised as unpredictable, uncontrollable, and overwhelming.
By administering these three scales concurrently, the clinicians could evaluate comorbidity — whether depression and anxiety were occurring together, and how directly they tracked daily academic stress.
The depression findings: 33.6% past the clinical line
The core finding of Parihar et al. centered on the distribution of PHQ-9 scores.
Of the 250 students evaluated, only 28.4% fell into the "minimal or no depression" category (scores 0–4). The remaining 71.6% reported depressive symptomatology of varying intensity: - Mild depressive symptoms (Score 5–9): 38.0% - Moderate depression (Score 10–14): 21.2% - Moderately severe depression (Score 15–19): 9.6% - Severe clinical depression (Score 20–27): 2.8%
Combining the moderate, moderately severe, and severe tiers yields the study’s headline statistic: 33.6% of students crossed the clinical diagnostic threshold (PHQ-9 ≥ 10).
To put that in perspective, the National Mental Health Survey of India (NMHS 2015–16) estimated the lifetime prevalence of depressive disorders among urban Indian adolescents and young adults at between 3.5% and 5.2%. The rate observed in the Kota coaching sample was roughly six times higher than the national baseline for the same demographic cohort.
The qualitative findings within the PHQ-9 responses revealed pervasive symptoms: chronic fatigue unalleviated by rest, sustained anhedonia (the inability to experience pleasure in daily activities), recurrent feelings of guilt regarding parental sacrifices, and difficulties sustaining attention during lecture hours.
Anxiety, perceived stress, and the repeater multiplier
Depressive symptoms did not appear in isolation. The study recorded elevated comorbidity with generalized anxiety disorder and acute subjective stress.
Using the GAD-7 scale, 41.2% of participants crossed the clinical cutoff for moderate-to-severe anxiety (score ≥ 10). When correlating GAD-7 and PHQ-9 outcomes, the researchers observed a statistically significant positive correlation (r = 0.68, p < 0.001): students experiencing severe panic, anticipatory exam dread, or physical tremors were overwhelmingly likely to suffer from depressive symptoms as well.
On the PSS-10 scale, over 62% of respondents scored in the "high perceived stress" band (scores 27–40), demonstrating a pervasive loss of personal agency and perceived inability to manage cumulative workloads.
Crucially, the study analyzed demographic and academic variables to identify which students faced the highest vulnerability: - The Repeater Multiplier: Students on their second or third "drop year" demonstrated significantly higher mean depression scores (mean PHQ-9: 12.4) compared to first-time Class 12 foundation students (mean PHQ-9: 7.8). Having failed a previous attempt, repeaters operate under compounded shame, heightened financial guilt, and the social dread of returning empty-handed. - Physical Isolation: Students living alone in single-room PG accommodations without communal recreation spaces scored significantly higher on anxiety measures than those in double-occupancy rooms with peer companionship.
The physiological toll: Chronic sleep deprivation
One of the most consequential clinical contributions of the Parihar et al. study was documenting the biological correlates of coaching routines — specifically chronic sleep restriction.
Medical guidelines universally prescribe 7 to 9 hours of restorative sleep per night for adolescents aged 15 to 19 to support neuroplasticity, memory consolidation, and emotional regulation.
In the Kota cohort: - 72.4% of students reported sleeping fewer than 6 hours per night. - Over 24% reported sleeping fewer than 5 hours per night, routinely utilizing caffeinated tablets or energy drinks to sustain late-night study cycles between 1:00 AM and 5:30 AM. - 48.8% reported sleep onset latency exceeding 45 minutes, indicating significant clinical insomnia driven by cognitive arousal and anticipatory test anxiety.
The researchers emphasized that chronic sleep deprivation is not merely an incidental side effect of competitive preparation; it is an active neurobiological accelerant of affective disorders. Persistent sleep deficits impair prefrontal cortex inhibition over the amygdala, dramatically amplifying emotional reactivity, panic, and depressive despair.
Why peer review matters: Validating the TISS baseline
The broader significance of the Parihar et al. paper lies in scientific triangulation.
In empirical research, a single report — no matter how well executed — can be dismissed as an outlier, politically motivated, or methodologically flawed. The 2018 TISS report was an administrative document commissioned by the Rajasthan government.
When an independent clinical team, using a different sample four years later, subjected to peer review in an indexed medical journal, arrives at virtually the exact same prevalence metric — 32.0% in TISS vs. 33.6% in Parihar et al. — the finding shifts from a contested claim into an empirically robust clinical reality.
The data demonstrates that elevated psychological distress in Kota is neither an anecdotal media exaggeration nor a seasonal moral panic. It is a reproducible epidemiological phenomenon embedded within the structural parameters of 16-hour daily routines, unrelenting relative ranking, and extreme stakes.
What this study doesn't prove
That coaching caused every case of depression. As a cross-sectional study, Parihar et al. recorded mental health states at a single point in time. It did not conduct baseline psychiatric evaluations on students before they left their hometowns. Some students may have had pre-existing vulnerabilities, family histories of affective disorders, or pre-morbid dysthymia that manifested in Kota.
That all students in Kota require psychiatric medication. A score above 10 on the PHQ-9 indicates moderate depressive symptomatology requiring clinical evaluation; it does not mandate pharmacological intervention. Many students in this category respond effectively to sleep restoration, schedule reduction, cognitive behavioral counseling, and social support.
That Kota is uniquely worse than other high-intensity test hubs. The study was situated solely in Kota. It did not run a parallel control arm assessing JEE/NEET aspirants studying at corporate coaching centers in Hyderabad, Delhi, or Patna. The psychological toll could be comparable in any competitive test-prep enclave in India.
That academic ambition is inherently pathological. Striving for admission into prestigious medical and engineering colleges is an understandable aspiration for upward social mobility. The study documents that the unmoderated, sleep-deprived conditions under which this preparation occurs create substantial psychiatric risk.
