Jailed Individuals’ Procedural Justice & Suicidal Ideation – Comprehensive Study Notes

Introduction & Public-Health Context

Suicide is the leading cause of death in U.S. jails (vs. 10th in the general population).
- 2018 jail suicide mortality: $45/100{,}000$ – more than twice the community rate $22/100{,}000$ .
- ~30 % of all in-custody deaths are suicides.
Suicidal ideation (SI) is estimated to be ≈30× more prevalent than completed suicide.
Lack of comprehensive national data on SI or suicide attempts inside U.S. corrections.
High SI rates threaten both institutional safety and individual well-being; SI often precedes attempts and fatalities.

Key Individual & Environmental Correlates of Self-Injurious Thoughts/Behaviors (SITB)

Individual risk factors repeatedly identified:
- Prior suicide attempts
- Mental-health disorders – depression, loneliness, anxiety
- History of trauma
Environmental/"pains of imprisonment" factors:
- Higher security level & isolation
- Violence/victimization threats
- Deprivations of autonomy & safety
Research gap: perceptions of fair treatment (procedural justice) inside facilities and their link to SITB.

Procedural Justice (PJ) Framework

Rooted in the process-based model of self-regulation (Leventhal 1980; Lind & Tyler 1988; Tyler 2006).
Core components
- Consistency of decision rules
- Voice: chance to tell one’s side
- Respect & dignified treatment
When legal actors treat subordinates fairly, people grant legitimacy and comply voluntarily.
Extensively validated for police & courts; recent extension to corrections.
- Shows links to rule adherence, legitimacy, lower misconduct, and improved mental-health outcomes.

Prior Empirical Evidence Linking PJ & Well-Being

Liebling et al. (2005): English/Welsh prisons – perceptions of injustice → distrust → higher suicide rates.
Slotboom et al. (2011): Dutch women – disrespect ↠ ↑ depression/PTSD/self-harm thoughts.
Beijersbergen et al. (2014): PJ at Time 1 predicted fewer mental-health problems at Time 2 (Dutch men).
Howard & Wakeling (2020): English/Welsh survey – lower PJ correlated with self-harm/suicide attempt (bivariate).
No U.S. jail study directly testing PJ → suicidal ideation before the present work.

Aims & Hypotheses of Current Study

Research Question: Are higher PJ perceptions associated with lower frequency of suicidal ideation among jailed adults in the United States?
Hypothesis: PJ will negatively predict SI frequency (i.e., more PJ → less SI).
Adds to ideation-to-action literature; offers criminal-justice–based intervention levers.

Methods Overview

Sample & Setting

Two county jails (Florida & Texas), data collected Mar 2018–Mar 2019.
Eligibility: ≥18 yrs, English-speaking, not in segregation/mental-health units.
548 surveys returned; final analytic N = 397 (after missing-data screening).
Response rate ≈ 26.6 % (consistent with prior jail self-report studies).

Participant Profile

72 % male; mean age ≈ 35 yrs.
44 % White; remaining Black, Hispanic, or other.
78 % reported prior suicide attempt; 23 % reported current-jail SI.
10 % reported self-injury in jail; 70 % endorse drug abuse history; 50 % alcohol problems.
22 % family history of suicide; 61 % family criminality; 20 % violent instant offense.

Measures

Dependent Variable: Suicidal Ideation (SITBI-J single item)
- Frequency scale (1 = Never … 4 = Often) → treated as ordered outcome.
Key Independent Variable: Procedural Justice Index (3 items; $\alpha = .779$ )
- Voice (“chance to tell your side”)
- Respect (“treat inmates fairly & with respect”)
- Consistency (“how often officers treat inmates fairly”)
Covariates
- Prior suicide attempt (yes/no)
- Self-harm in jail (Likert 1–4)
- Social support (3 items, $\alpha=.925$ )
- Hopelessness (9 items, $\alpha=.834$ )
- Loneliness (single item)
- Substance abuse: Drug (yes/no); Alcohol (CAGE-based index $\alpha=.849$ )
- Family suicide & crime history, demographics, violent offense status, education, relationship, parenthood.

Analytic Strategy

Ordered logistic regression (ologit) chosen for ordered 4-category DV.
Brant test confirmed proportional-odds assumption.
Reported adjusted odds ratios (aOR); significance at p<.05.

Key Results

Model fit: LR $\chi^{2}=157.94$ ; Pseudo $R^{2}=.2465$ .
Procedural Justice
- $b=-1.66,\; p=.001;\; aOR=0.190\; (95\%\ CI\;0.105–0.341)$
- $+1$ SD in PJ → 81 % lower odds of belonging to a higher-frequency SI category.
Significant Covariates (direction & magnitude)
- No prior suicide attempt: $aOR=0.665$ (protective)
- Self-harm in jail: $aOR=2.54$
- Hopelessness: $aOR=2.75$
- Loneliness: $aOR=2.16$
- Drug abuse history: $aOR=3.26$
- Family crime history (absent): $aOR=0.461$ (protective)
- White race: $aOR=0.427$ (lower SI frequency than non-White peers)
Non-significant: Social support, violent offense, age, gender, education, alcohol abuse (in multivariate model).

Discussion – Major Takeaways

Fair & respectful officer treatment is a potent correlate of lower jail SI, independent of robust clinical predictors (previous attempts, hopelessness).
Supports ideation-to-action prevention logic: altering jail climate may curb lethal behaviors before escalation.
Adds U.S. jail evidence to UK/EU findings; demonstrates process-based legitimacy matters behind bars.
Seven auxiliary factors align with broader SITB literature (hopelessness, loneliness, drug abuse, etc.).
- Noteworthy protective role of family criminality (possible acclimation/vicarious learning effect).
- Race effect opposite to national suicide-death patterns – may reflect group-value model or facility racial dynamics.

Policy & Practice Implications

Procedural-Justice Training for Correctional Officers
- Low-cost strategy with documented success in policing; likely transferable to corrections.
- Emphasize voice, respectful dialogue, consistent rule enforcement.
Screening & Intervention Windows
- Identify individuals with low PJ perceptions + traditional risk markers; offer cognitive or dialectical behavior therapy early in custody.
Cultural/Anti-Bias Reforms
- Combat racial inequities; implicit-bias & PJ combined trainings can maximize legitimacy and safety.
Data Collection Enhancements
- Routine monitoring of SI, attempts, and PJ across facilities to guide targeted prevention.

Limitations

Two jails; suburban context – limits generalizability.
Cross-sectional design precludes causal inference or temporal ordering.
Some missing data (not MCAR); offense-type item differed across sites.
3-item PJ scale – future work should validate expanded measures; include pre-custody attitudes.
Did not capture adjudication status; potential variation in PJ/SI by pre-trial vs. sentenced.

Future Research Directions

Longitudinal & mixed-methods designs to track PJ changes and SI trajectories over time.
Larger, more diverse jail/prison samples to test racial mediation, group-engagement model, and facility-level moderators (e.g., staff demographics, unit culture).
Experimental PJ training evaluations inside corrections – measure downstream effects on SI, self-harm, misconduct, and institutional climate.
Integration with psychological theories (e.g., Interpersonal Theory of Suicide, 3-Step Theory) to test PJ as a contextual thwarted belongingness or capability factor.

Key Numerical & Statistical Highlights

Jail suicide mortality: $\frac{45}{100{,}000}$ vs. community $\frac{22}{100{,}000}$ .
Procedural Justice effect: $aOR=0.190$ (~81 % reduction in odds per unit increase).
Hopelessness effect: $aOR=2.75$ .
Drug abuse effect: $aOR=3.26$ .
72 % of prison suicide decedents showed prior SI in post-mortem autopsy (He et al. 2001).
International SI prevalence in custody: 23.7 %–44 % reported by Belgian & Italian studies.

Ethical, Philosophical, & Real-World Significance

Upholding dignity in confinement aligns with human-rights ethics and may literally save lives.
Reinforces shift from purely deterrence/control models toward relational legitimacy in corrections.
Promotes holistic public-health approach: mental-health outcomes are intertwined with justice procedures.
