Participants
Participants were 163 inmates recruited from June 2002 to May 2007 as part of a larger longitudinal study (Tangney, Mashek, and Stuewig

Data were collected after entry into the jail (Time 1), again just before release to the community (Time 2), and then one year post-release (Time 3). Inmates were informed that participation was voluntary and that data were confidential, protected by a Certificate of Confidentiality from the Department of Health and Human Services (DHHS). Pre-release assessments (Time 2) were collected from 2002–2010, depending on inmates’ release dates. Post-release assessments (Time 3) were collected from 2003 to 2010. Inmates received a $15–18 honorarium for completing the Time 1 assessment, $25 for the Time 2 assessment, and $50 for the Time 3 assessment.
Of the participants who consented to participate in the parent study (N = 628), 120 were not eligible for longitudinal follow up because they were transferred, released, or bonded out before assessments could be completed. Of the 508 inmates enrolled in the longitudinal study, 86 people were disqualified because there were less than 6 weeks between intake and their release date and 12 people were considered not yet eligible for their pre-release assessment because they are still currently incarcerated. Of the participants, 410 were eligible to be re-interviewed prior to their release from jail/prison (Time 2). Of these participants, we were unable to reach 116 participants in the allotted time frame for their Time 2 assessment (timed out), five refused to complete the assessment, four withdrew from the study, and one person did not have a release date, so was excluded, leaving 284 participants who completed a Time 2 assessment.
A total of 163 participants completed valid assessments of one or both of the stigma measures prior to release (Time 2). Because the stigma measures were added into the study after data collection had begun, 60 participants did not receive these measures. Due to study design/unexpected release, we collected an abbreviated version for 25 participants, and a missed version for 31 participants after the allotted time frame for the Time 2 assessment. Stigma measures were not included in these versions because they were collected after participants had been released, and therefore the prospective stigma measure did not make sense. An additional five people were excluded from analyses for having invalid data.
Figure 1 shows a consort diagram for the Time 2 stigma measures. Participants (
N = 163) were about 33 years old on average (
range = 18.44–69.63) and primarily male (71.2%). This sample was racially/ethnically diverse (46.0% African American, 35.6% Caucasian, 6.1% Hispanic, 8.0% Mixed race/other race, 4.3% Asian/Pacific Islander).

This figure illustrates a consort diagram of sample retention from participants enrolled at Time 1 to those who completed the stigma measures prior to release from jail/prison. aParticipants were disqualified if there were less than 6 weeks between their Time 1 and Time 2 data collection. bParticipants timed out after a predetermined period of time allotted for each follow-up assessment. cStigma measures were added into the study after data collection had begun, causing missing data on the stigma measures.
This article focuses on pre-release (Time 2) and post-release (Time 3) data. Missing data were handled using Full Information Maximum Likelihood (FIML). Thus, we were able to analyze the entire sample of individuals (
N = 371) who completed the post-release measures. FIML is highly encouraged when data are Missing at Random, which means that participants are not missing on items/variables for a reason that is relevant to the phenomenon being measured (Schafer and Graham

View all references). In our sample, missingness is largely due to factors related to study design. Specifically, missingness was due to unexpected release from the jail, which occurred for various participants throughout the course of the study (
n = 56). Also, a proportion of data had already been collected at Time 2 before the stigma measures were introduced in our interview packet, resulting in missing data for 60 participants. In this case, the only identifiable variable related to missingness in our study was the date in which a person’s interview occurred; because participants were recruited into the study randomly, we do not think that this influences our missingness in any consistent way (Schafer and Graham
200259.
Schafer, Joseph L. and John W. Graham. 2002. “Missing Data: Our View of the State of the Art.” Psychological Methods 7:147–177.
[CrossRef], [PubMed], [Web of Science ®]
View all references). All participants who had the opportunity to complete the stigma measures completed them; five individuals’ stigma data were invalidated because they were erroneously administered outside the allowable timeframe or due to indications of invalidity from the Personality Assessment Inventory (PAI) validity scales.
To increase our confidence that our data were missing at random, we analyzed whether participants who completed the stigma measures were different in important ways compared to the participants who did not complete the stigma measures. Specifically, we conducted t-tests comparing participants who completed the stigma measures (n = 163) to those who did not (n = 121), on demographics and outcome variables. Results of t-tests show no significant differences on any demographic variables, suggesting the groups were equivalent in race, age, gender, and years of education completed. There were no significant differences on any outcome variables, suggesting that the groups were equivalent in levels of post-release employment, community functioning, substance dependence, and mental health symptoms. Because missing data was unrelated to the variables being measured in our study, as well as any other consistent variable, it was estimated during analyses.
The FIML technique is considered to be a more accurate approach to missing data than the commonly used listwise deletion method (Schafer and Graham
200259.

View all references). Listwise deletion of cases can strongly bias results because it deletes people who do not have complete data, which is not representative of the true population. It is almost impossible to predict whether listwise deletion will bias the results of any one study, and experts recommend not using the technique to avoid the possibility of bias (Schafer and Graham

198931.

[CrossRef], [Web of Science ®], [CSA]
View all references). The same premise applies here, where we estimate X for participants who have Y. FIML uses all of the data available about a participant, including other measures at that timepoint (i.e., missing stigma data is estimated using other data on that person at Time 2) and outcome measures to determine the model parameters. Data values are not imputed in this technique, but rather the model parameters are estimated using all available information.
Figure 2 shows a consort diagram for Time 3 outcome measures. The sample analyzed in FIML was descriptively similar to the sample of 163 people (
Mean age = 33,
range = 18.40–69.63; 70.1% male; 45.6% African American, 35.6% Caucasian, 7.0% Mixed race/Other race; 6.5% Hispanic, 3.5% Asian/Pacific Islander, and additionally there were 0.8% Mexican American, 0.5% Middle Eastern, 0.5% Native American participants in this larger sample).
Figure 2. Sample retention from Time 1 to FIML sample. This figure illustrates a consort diagram of sample retention from those enrolled at Time 1 to those who were analyzed with FIML analyses. The legend provides a detailed description of the sample. aFIML sample (N = 371) contained all 163 participants who completed the stigma measures at Time 2; of these 131 had complete Time 3 assessments, and 31 were missing data on Time 3. Of the remaining 208 participants, 60 participants completed a Time 2 and Time 3 assessment, but were missing stigma data at Time 2. The remaining 148 participants missed their Time 2 assessment entirely (various reasons like unexpected release), and yet had complete Time 3 data. All data were assumed to be missing at random.
Measures and procedures
A battery of measures and demographic questionnaires were given at entry into the jail (Time 1); race was the only variable used from this timepoint. Other assessments relevant to this study were given prior to release from jail/prison (Time 2) and one year post-release (Time 3) timepoints. Time 2 assessments were conducted in the privacy of professional visiting rooms or secure classrooms, and included perceived stigma, shame-proneness, optimism, and criminal identity. Perceived and anticipated stigma were assessed with the Inmate Perceptions and Expectations of Stigma measure (IPES; Mashek et al.
200242.
Mashek, Debra, Meyer, P., McGrath, J., Jeffrey Stuewig, and June P. Tangney. 2002. Inmate Perceptions and Expectations of Stigma (IPES). George Mason University, Fairfax, VA.
View all references) containing 12 items. Inmates were asked to indicate on a 7-point scale (“1” “totally disagree” to “7” “totally agree”) their perceptions of how people in society feel toward criminals—e.g., “People on the outside think criminals are bad people” (6 items; alpha = .83). Participants were then asked to indicate how they thought
they would be treated once released; for example, “People in the community will accept me” (4 items; alpha = .88). Previous factor analyses (Moore et al.

p < .001).

Shame-proneness was assessed using the Test of Self-Conscious Affect-Socially Deviant (TOSCA-SD; Hanson and Tangney

Hanson, Karl, R. and June P. Tangney. 1996. “The Test of Self-Conscious Affect-Socially Deviant Populations (TOSCA-SD).” Corrections Research, Department of the Solicitor General of Canada; Ottawa.
View all references). The TOSCA-SD is composed of 13 scenarios followed by a series of possible responses. Participants rated how likely they would be to respond in ways described (capturing shame and guilt responses). This measure has been shown to be reliable and valid with offenders (Tangney et al.
201168.

View all references). The shame-combined scale, including negative self-appraisal responses (e.g., “You would think, I’m inconsiderate”) and behavioral avoidance responses (e.g. “You would leave as quickly as you could”), was used for these analyses. The TOSCA-SD shame-proneness scale had acceptable reliability (alpha = .77) and was normally distributed (see ). Optimism was assessed using six items from the Values in Action inventory (VIA; Peterson and Seligman
200150.

View all references). This scale has been shown to be reliable and valid with inmates (Heigel, Stuewig, and Tangney

View all references). This scale assessed trait optimism (e.g., “I can always find the positive in what seems negative to others”). Responses were rated on a 5-point Likert scale where “1” was “not at all like me” and “5” was “very much like me” (alpha = .77). This scale was normally distributed (see ).
Two aspects of social identity were assessed. The Inclusion of Community in Self scale (ICS; Mashek, Cannaday, and Tangney

View all references) assessed actual and desired connectedness with various target groups including the family, the criminal community, and the community at large. Responses were rated using six figures of circles overlapping to various degrees (representing not at all connected to as connected as possible). The item asking participants about their
actual connectedness with the criminal community was used in the current analyses. The ICS has been determined to be valid with inmates, although test–retest data was not available to assess reliability (Mashek et al.
200643.

[CrossRef], [PubMed], [Web of Science ®]
View all references). About 37% of participants indicated no connectedness to the criminal community, slightly skewing this variable (see ). Participants were also asked to what degree they agreed with the statement “I am a criminal” on a 6-point Likert scale from “1” “totally disagree” to “6” “totally agree.” This variable was slightly kurtotic due to a concentration of data points at the low (especially) and high ends of the scale (see ).
Time 3 assessments were conducted by phone or (for those re-incarcerated) in person one year after inmates were released from jail/prison, and included employment, recidivism, mental health symptoms, substance dependence symptoms, and community functioning. Employment was assessed by asking participants whether they were unemployed, or had odd jobs, part-time (less than 35 hours), or full-time employment (more than 35 hours) in the year after release from jail, and how many weeks they worked in that year. The majority of participants (67.1%) reported having full-time employment in the year after release. A continuous variable (total hours employed) was created by multiplying the number of hours expected for the type of employment (i.e., typical number of hours worked in full-time employment in the United States is 40 hours, part-time employment is 20 hours, and odd jobs is 5 hours) by the number of weeks participants were employed in the year after release. The distribution covered the full range and showed minimal skewness and kurtosis (see ), although there were substantial clusters at the extreme ends of the distributions reflecting unemployed and full-time employed participants.
Recidivism was assessed by both self-report and official records. Participants were asked whether they had been arrested for (self-reported arrests) and whether they had committed without being detected (self-reported offenses) each of 16 types of crime (i.e., theft, robbery, assault, murder, domestic violence, weapons offenses, major driving offenses, prostitution, drug offenses, sex offenses, fraud, kidnapping, arson, resisting arrest, miscellaneous, and other) during the year after their release. Official National Crime Information Center (NCIC) criminal records of arrests in the first year after release were collected as well (official arrests); 119 charge codes found on official records were categorized into the 16 types of crimes used for the self-report variables. To capture criminal versatility in these three sources, three variables were created to reflect the number of types of crimes (i.e., 0–16) that participants were arrested for (official arrests and self-reported arrests) and reported committing (self-reported offenses). Versatility (the number of different types of crimes) was employed rather than the frequency of arrest/offense because the latter is confounded by the type of crime (e.g., illegal substance use vs. violent offenses). The actual range for these variables were 0–5 for self-reported arrests, 0–6 for official records of arrest, and 0–9 for self-reported offenses. Because many participants reported/were found to have zero arrests and reported committing zero offenses, each variable was skewed (see ).
Eight items representing community participation/functioning were chosen from a measure of detailed demographic information given at the one year post-release assessment. Items included (1) residential stability, (2) homeownership, (3) current marital status, (4) largest source of support in the past year (i.e., job, family/spouse, friends, illegal activities, unemployment benefits, etc.), (5) valid driver’s license, (6) financial support of children, (7) educational and vocational upgrades (i.e., taking vocational or college courses, graduating high school, getting a Graduate Equivalency Diploma [GED], etc.), and (8) volunteerism in the community. Participant responses on each of the eight items were evaluated in terms of the level of adaptive functioning. We used the criminology literature to indicate certain responses as being adaptive, prosocial behaviors that are particularly useful for offenders’ reintegration in the community. All other behaviors, including maladaptive ones and even neutral ones that could be adaptive or maladaptive depending on the situation, were considered fundamentally different and placed in another category.
Responses deemed to be adaptive were given a score of 1, and those that were either neutral or maladaptive were given a score of 0. Specifically, for residential stability, living in 1 or 2 places in the year post-release was considered adaptive and living in more than 2 places or being homeless was considered neutral/maladaptive. There is a general consensus in the literature of measuring residential stability with the number of places lived. For current marital status, being legally married was the only response considered adaptive. Social control theory (in criminology) states that the act of being legally married to someone is a community convention that is fundamentally different from other forms of cohabitation or relationships (Laub, Nagin and Sampson 1993). It is believed that this represents a prosocial bond to the community that is not observed in cohabitating couples or other types of romantic relationships.
For largest source of financial support, a job or savings was considered adaptive and all other responses were considered neutral (i.e., family, spouse) or maladaptive (i.e., illegal activities). Research in criminology places great importance on the employment of ex-offenders after release from jail, and supporting oneself through a job or savings is considered the primary prosocial form of financial support. For financial support of children, supporting all of their children or more than their own children (i.e., a partner’s children) was considered adaptive, not having children was considered neutral, and failing to financially support all of their children was considered maladaptive. In regard to supporting one’s children, we do not think of it as penalizing those without children, but rather giving credit to those with children who also financially support their children. For educational and vocational upgrades, participating in any of the upgrades was considered adaptive and not participating in any was considered neutral/maladaptive. On yes/no questions, participants who reported owning their own home, having a valid driver’s license, or volunteering in the community in the past year were given a score of 1 (adaptive) on those respective items. Scores were averaged across the eight dichotomous indicators to create a total functioning index. Because this is a formative construct composed of different areas of functioning that are not necessarily expected to be correlated with one another (i.e., having a valid driver’s license may not necessarily be linked to financially supporting one’s children), Cronbach’s alpha was not calculated.
Levels of mental health symptoms were assessed with a shortened version of the Personality Assessment Inventory (PAI; Morey
200746.
Morey, Les C. 2007. Personality Assessment Inventory: Professional Manual (2nd ed.). Odessa, FL: Psychological Assessment Resources.
View all references), which included four scales: depression (DEP), anxiety (ANX), borderline features (BPD), and stress (STR). Item responses ranged from 1 = “False, not at all true” to 4 = “Very true.” These scales use
T-scores, which are normed on a sample of average adults; the ranges for each scale were 36T–90T for depression (24 items, α = .85), 34T–89T for anxiety (24 items, α = .89), 36T–94T for borderline features (24 items, α = .88), and 37T–91T for stress (8 items, α = .74). The PAI is a widely used, well-validated measure (Morey

View all references) Texas Christian University: Correctional Residential Treatment Form, Initial Assessment (TCU-CRTF), four substance dependence scales were created to capture symptoms of dependency on alcohol, marijuana, cocaine, and opiates in the first year post-release. Each variable was composed of items that assess each of the DSM-IV-TR substance dependence domains. Item responses ranged from 0 = “Never” to 4 = “7 or more times.” Responses were averaged within domain and a total score was computed by taking the mean across the seven domains (six in the case of marijuana because withdrawal is not considered part of the criteria). Each scale had acceptable reliability (alcohol, 7 items, α = .93; marijuana, 6 items, α = .88; opiates, 7 items, α = .97; cocaine, 7 items, α = .98). Given the similarities between cocaine and opiates (illegal, highly addictive) and the low rate of opiate use in our sample, opiates and cocaine were combined into a category of hard drugs. Frequency and dependence of cocaine/opiate use was defined as the higher of the two ratings for either cocaine or opiates. As there were a large number of people with very few dependency symptoms, each variable was skewed (see ). The TCU has been shown to be reliable with jail inmates (Stuewig et al.
