RESUMO

BACKGROUND: Given high rates of cancer mortality in Native communities, we examined how urban American Indian and Alaska Native elders talk about colorectal cancer (CRC) and CRC screening. METHODS: We conducted seven focus groups with a total of 46 participants in two urban clinics in the Pacific Northwest to assess participant awareness, perceptions, and concerns about CRC and CRC screening. Using speech codes theory, we identified norms that govern when and how to talk about CRC in this population. RESULTS: Our analyses revealed that male participants often avoided screening because they perceived it as emasculating, whereas women often avoided screening because of embarrassment and past trauma resulting from sexual abuse. Both men and women used humor to mitigate the threatening nature of discussions about CRC and CRC screening. CONCLUSIONS: We offer our analytic results to assist others in developing culturally appropriate interventions to promote CRC screening among American Indians and Alaska Natives.

RESUMO

BACKGROUND AND OBJECTIVES: A "revolving door" of repeated admissions to detoxification treatment facilities has long plagued alcohol and drug use patients, yet few studies examine factors associated with readmission. This study examined risk factors for readmission to alcohol and opioid detoxification in a sample from the Alaska Interior. METHODS: Data were extracted from electronic medical records for admissions between 2012 and 2016 at an inpatient detoxification facility in Fairbanks, Alaska. Data from 1014 patients admitted for alcohol detoxification and 267 patients admitted for opioid detoxification were analyzed. The analysis employed descriptive statistics for risk factors (substance use history, adverse life experiences, and psychosocial functioning) and prevalence of readmission to either alcohol or opioid detoxification. Inferential analyses used marginal standardization to calculate differences in readmission risk by patient characteristics. RESULTS: Male, Alaska Native/American Indian, single-never married patients, and those seeking work were at higher risk for readmission to alcohol detoxification, while those with stable housing were at reduced risk. Being single-never married and completing detoxification treatment reduced readmission to opioid detoxification. Family involvement in detoxification reduced readmission risk for both alcohol and opioid patients. DISCUSSION AND CONCLUSIONS: Further research that investigates the mechanism(s) by which family may act as a protective factor may be efficacious in eliminating the "revolving door" of detoxification. SCIENTIFIC SIGNIFICANCE: This study is the first to examine both alcohol and opioid use risk and protective factors in the Alaska Interior. The results can be used in the development of interventions for subpopulations with high detoxification readmission rates.

RESUMO

BACKGROUND: Alcohol-exposed pregnancy (AEP) is an ongoing concern, especially within low-resource, high-risk areas such as rural American Indian/Alaska Native (AIAN) communities. Brief, preconceptual AEP-reduction interventions are popular in such areas but have a small impact on alcohol use. Developing a strategic alcohol change plan is a key program component; however, there is little research on strategy selection, especially within contexts that positively or negatively impact selection (e.g., cultural strengths, trauma, collective efficacy within AIAN communities). This study qualitatively analyzed strategies chosen to reduce alcohol use by AIAN women participating in a culturally tailored, brief, preconceptual AEP-reduction intervention. METHODS: One hundred-sixty Northern Plains AIAN women who were participating in a brief AEP-reduction program developed a plan to accomplish an alcohol reduction/abstention goal at the first and last program sessions. The plan included choosing 1 or more strategies to (1) achieve the goal, (2) mitigate barriers, and (3) use cultural strengths. Qualitative analysis of the data involved thematic open and structured coding of all 3 strategies separately. We also examined how many different themes (different individual strategies) participants reported for each strategy component. RESULTS: Most participants reported only 1 strategy (theme) for each of the 3 components. Common goal-achieving and barrier-mitigation strategies included positive social supports and avoiding negative or alcohol-involved social environments. Other strategies involved circular logic (e.g., the strategy to reduce drinking was to drink less). Both traditional and western cultural strengths were reported as important resources, although many participants had no cultural resource strategy. CONCLUSION: Programs aimed at reducing AEPs may need to provide participants more support to develop strong strategies to reduce alcohol use when implemented within areas with high levels of trauma and contextual barriers that can impact strategy selection. Such support could include ways to improve health on both interpersonal and community levels.

RESUMO

BACKGROUND: The preconception period provides a unique opportunity to optimize the health of women and children. High rates of alcohol use and unintended pregnancies are common across many Western societies, and alcohol-exposed pregnancies (AEPs) are a possible unintended outcome. The aim of the current study was to evaluate preconception interventions for the prevention of AEPs. METHODS: A systematic search of four electronic databases (PubMed, Embase, CINAHL, and PsycINFO) was undertaken for relevant peer-reviewed articles published from 1970 onward. Studies were included if they enrolled women and/or their support networks during the preconception period. RESULTS: Nineteen studies met the inclusion criteria. The majority of studies (n = 14) evaluated CHOICES-based interventions, which incorporate motivational interviewing approaches to change alcohol and/or contraceptive behavior. The other five interventions included a range of different approaches and modes of delivery. The majority of interventions were successful in reducing AEP risk. Changes in AEP risk were more often driven by changes in contraceptive behavior, although some approaches led to changes in both alcohol and contraceptive behavior. CONCLUSIONS: The review indicated that many interventions were efficacious at reducing AEP risk during the preconception period through preventing unplanned pregnancy. The effectiveness estimated from these clinical trials may be greater than that seen in interventions when implemented in practice where there is a lack of blinding and greater attrition of participants during follow-up. Further research investigating the real-world effectiveness of these intervention approaches implemented across a wide range of clinical settings would be beneficial.

RESUMO

BACKGROUND: A tribally led Changing High-Risk Alcohol Use and Increasing Contraception Effectiveness Study (CHOICES) Program has successfully decreased the risk of alcohol-exposed pregnancies (AEPs) among adult American Indian/Alaska Native (AI/AN) women by either reducing risky drinking or increasing contraception use. However, a community needs assessment revealed a need to implement a similar intervention with AI/AN teens. The goal of the project was to develop and establish the acceptability of CHOICES for AI/AN teens. METHODS: Key informant interviews were conducted to review the existing OST CHOICES intervention. After modifications to the existing program, focus groups with AI/AN teens were conducted to ensure validity and to finalize the OST CHAT (CHOICES for American Indian Teens) intervention. RESULTS: Key informant (N = 15) participants suggested that a Web-based intervention may increase teen engagement by making the intervention more interactive and visually stimulating. Based on this formative research, CHAT was developed via Research Electronic Data Capture (REDCap). Feedback on the online CHAT curriculum was given by focus groups comprised of AI/AN adolescents, and participants felt that this type of intervention would be both acceptable and able to implement with a community of reservation-based teens. CONCLUSIONS: This study outlines the development of a Web-based intervention for an AEP intervention for AI/AN teens and will inform future prevention efforts. Implications include an expansion of the evidence-based CHOICES intervention for AI/AN teens and also development of a Web-based intervention for rural, reservation-based AI/AN communities.

RESUMO

Ticagrelor is an antagonist of both platelet adenosine diphosphate (ADP) receptor P2Y12 and equilibrative nucleoside transporter-1. Optimal timing of ticagrelor cessation prior to coronary artery bypass grafting (CABG) remains unclear. We characterized the offset of ticagrelor's effects on platelets and cellular adenosine uptake in ticagrelor-treated patients (n = 13) awaiting CABG. Blood was drawn prior to CABG at multiple timepoints 2 to 120 (h) after the last dose of ticagrelor. Platelet function (n = 13) was assessed with multiple electrode aggregometry (MEA), expressed as arbitrary units (U) derived from area-under-the-curve (AUC) in response to ADP, and inhibition of adenosine uptake by high-performance liquid chromatography (n = 7). Mean±SD AUC was 20.3 ± 8.2 U (2 h post-ticagrelor), 33.0 ± 18.3U (24 h), 56.6 ± 30.6U (48 h), 61.4 ± 20.2U (72 h), 82.8 ± 24.2U (96 h) and 96.0 ± 15.3U (120 h). There was a significant difference between 72 h and 120 h (p = .007), but not between 96 h and 120 h (p > .99). By 96 h, all patients had AUC >31U, an accepted cutoff below which surgical bleeding risk is increased. Adenosine uptake showed no significant differences between the timepoints. These data suggest it takes 4 days for platelet reactivity to recover sufficiently after cessation of ticagrelor to avoid the excess risk of CABG-related bleeding. Discontinuing ticagrelor had no measurable effect on cellular adenosine uptake.

RESUMO

Rates of posttraumatic stress disorder (PTSD) are three times higher in traumatically injured populations than the general population, yet limited brief, valid measures for assessing PTSD symptom severity exist. The PTSD Checklist for DSM-5 (PCL-5) is a valid, efficient measure of symptom severity, but its completion is time consuming. Subsequently, abbreviated four- and eight-item versions were developed using the Mini-International Neuropsychiatric Interview-7 PTSD module and validated in Veteran samples. This study aimed to validate these abbreviated versions using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), the gold standard for PTSD diagnosis, in a traumatically injured civilian population. Participants were 251 traumatically injured adults (Mage = 42.52 years; 69.3% male; 50.2% Caucasian) recruited from a Level 1 trauma center inpatient unit; 32.3% and 17.9% of participants experienced a motor vehicle crash or gunshot wound, respectively. The CAPS-5 and PCL-5 were administered approximately 6.5 months postinjury. We examined whether compared to the full PCL-5, the abbreviated versions would adequately differentiate between participants with and without a CAPS-5 PTSD diagnosis. The abbreviated versions were highly correlated with the total scale and showed good-to-excellent internal consistency. The diagnostic utility of the abbreviated measures was comparable to that of the total scale regarding sensitivity, suggesting they may be useful as abbreviated screening tools; however, the total scale functioned better regarding specificity. The abbreviated versions of the PCL-5 may be useful screening instruments in the long-term care of traumatic injury survivors and may be more likely to be implemented across routine clinical and research contexts.

RESUMO

Higher aspirin doses may be inferior in ticagrelor-treated acute coronary syndrome (ACS) patients and reducing bleeding risk whilst maintaining antithrombotic benefits could improve outcomes. We characterized the pharmacodynamics of a novel dual-antiplatelet-therapy regimen consisting of very-low-dose twice-daily (BD) aspirin with standard-dose ticagrelor. A total of 20 ticagrelor-treated ACS patients entered a randomized crossover to take aspirin 20 mg BD (12-hourly) during one 14-day period and 75 mg once-daily (OD) in the other. After 14 days of treatment, serum thromboxane (TX)B2 and light-transmittance aggregometry were assessed pre- and 2 h post-morning-dose, bleeding time was measured post-dose, and TXA2 and prostacyclin stable metabolites were measured in urine collected 2 h post-morning-dose. Data are expressed as mean ± SD. After 14 days treatment, serum TXB2 levels were significantly greater 2 h post-dosing with aspirin 20 mg BD vs. 75 mg OD (3.0 ± 3.6 ng/mL vs. 0.8 ± 1.9 ng/mL; p = 0.018) whereas pre-dosing levels were not significantly different (3.5 ± 4.1 ng/mL vs. 2.5 ± 3.1 ng/mL, p = 0.23). 1-mmol/L arachidonic acid-induced platelet aggregation was similarly inhibited by both regimens pre-dose (8.5 ± 14.3% vs. 5.1 ± 3.6%, p = 0.24) and post-dose (8.7 ± 14.2% vs. 6.6 ± 5.3%; p = 0.41). Post-dose bleeding time was shorter with 20 mg BD (680 ± 306 s vs. 834 ± 386 s, p = 0.02). Urinary prostacyclin and TX metabolite excretion were not significantly different. In conclusion, compared to aspirin 75 mg OD, aspirin 20 mg BD provided consistent inhibition of platelet TXA2 release and aggregation, and improved post-dose hemostasis, in ticagrelor-treated ACS patients. Further studies are warranted to assess whether this regimen improves the balance of clinical efficacy and safety.

RESUMO

Sound duration is important in acoustic communication, including speech recognition in humans. Although duration-selective auditory neurons have been found, the underlying mechanisms are unclear. To investigate these mechanisms we combined in vivo whole-cell patch recordings from midbrain neurons, extraction of excitatory and inhibitory conductances, and focal pharmacological manipulations. We show that selectivity for short-duration stimuli results from integration of short-latency, sustained inhibition with delayed, phasic excitation; active membrane properties appeared to amplify responses to effective stimuli. Blocking GABAA receptors attenuated stimulus-related inhibition, revealed suprathreshold excitation at all stimulus durations, and decreased short-pass selectivity without changing resting potentials. Blocking AMPA and NMDA receptors to attenuate excitation confirmed that inhibition tracks stimulus duration and revealed no evidence of postinhibitory rebound depolarization inherent to coincidence models of duration selectivity. These results strongly support an anticoincidence mechanism of short-pass selectivity, wherein inhibition and suprathreshold excitation show greatest temporal overlap for long duration stimuli.

RESUMO

INTRODUCTION: Individual health is influenced by multiple, potentially correlated factors including healthcare availability, community context, and socioeconomic factors. To measure the health changes at county-levels across North Dakota, South Dakota, and Minnesota, a measure of relative health, health index, was developed incorporating multiple indicators from domains of health conditions, health behaviors, and social determinants. METHODS: We combined data from all 206 counties in the aforementioned three states for the years 2008-2012 from multiple data sources. We performed factor analysis that accounted for a hierarchical structure of the overall health index comprising of 15 indicators. RESULTS: A hierarchical structure is identified in which three intermediate factors are connecting the health index with 15 health indicators. The grouping results of the 206 counties based on health index values demonstrate the existence of a gradient in health conditions in the Northern Plains. CONCLUSIONS: The health status of urban areas was generally better than that of rural areas in the Northern Plains during this study period. The developed index adds stability to the estimates of the population characteristics, especially in rural, sparsely populated counties.

RESUMO

BACKGROUND: Fetal alcohol spectrum disorders are a major public health concern including among American Indian (AI)/Alaska Native (AN) communities. Various studies have demonstrated higher alcohol consumption among AI/AN women during pregnancy compared with other groups. This study intends to understand the milieu within which such consumption patterns flourish. The study utilizes qualitative and quantitative data from the Oglala Sioux Tribe (OST) CHOICES Program, a tribally run public health program that aims to reduce alcohol-exposed pregnancy preconceptually in AI women. METHODS: Alcohol consumption pattern (n = 264) is analyzed using descriptive statistics. Consumption patterns included average drinks consumed daily, their choice of drinks (beer, whiskey, wine, etc.), how much money participants were spending on alcohol and amount of calories consumed from alcohol. Qualitative data analysis included open coding of data from decisional balance exercise of the CHOICES program that looked at good things and not so good things about participants' drinking. RESULTS: Women reported drinking an average of 12 drinks daily, ranging between 1 and 86. Women drinking at home spent a median of $4,320 and $12,960 if drinking at a bar. A median of 1,200 calories per day from alcohol was reported. More women reported drinking beer compared with other types of alcohol within a domestic setting. Qualitative data analysis identified positive and negative aspects of drinking among the participants of OST CHOICES Program. Positive aspects included escaping from problems, socializing, and relaxation. Negative aspects included impact on families and domestic violence. CONCLUSIONS: While understanding their milieu, our study also unraveled different struggles (such as violence, peer pressure, financial burden, and depression) encountered by Native women in their daily lives. According to the participants, positive aspects of drinking outweigh the negative aspects and they viewed their drinking as a solution and not a problem.

RESUMO

BACKGROUND: Evaluating addiction wellness encompasses more than sobriety. The Recovery Capital Index (RCI), developed by Face It TOGETHER (FIT), measures addiction wellness using three domains and 22 components providing a comprehensive baseline and assessment of intervention effectiveness to allow for the tracking of client progress and to tailor support. The RCI is a holistic, person-centered metric irrespective of a person's treatment modality, recovery, or wellness pathway. METHODS: FIT and Sanford Research set a goal to validate the RCI's effectiveness to measure the factors associated with addiction wellness through a retrospective cohort study of FIT clients with the disease of addiction to alcohol and/or other drugs. Study cohort included 154 client intake records with corresponding RCI scores. The RCI was subjected to descriptive analyses using stacked barplots and side-by-side boxplots. The Cronbach and correlation coefficients were used to check the reliability and validity of the components within each domain. Differences of RCI against clients' characteristics were examined using Tukey's test of multiple comparisons of means. RESULTS: The validation process verified the design of the RCI domains - personal, social, and cultural capital. Variables significantly related to addiction wellness, based on the RCI, are: primary addiction, addiction identification, employment, and income. The RCI accurately described the individual's current state of recovery. CONCLUSIONS: This project validated the RCI as a tool to measure addiction wellness. The RCI measures what it is intended to measure. The results allow FIT and Sanford Research to next validate the RCI instrument's predictive nature for measuring behavior change.

RESUMO

BACKGROUND: Fetal alcohol spectrum disorders (FASD) comprise a continuum of lifelong outcomes in those born prenatally exposed to alcohol. Although studies have shown no differences in rates by race, FASD is of particular concern for American Indian communities. One tribally run prevention program is the Oglala Sioux Tribe (OST) CHOICES Program, which is modeled after the evidence-based CHOICES program that was focused on preconceptional prevention of alcohol-exposed pregnancy (AEP) by reducing risky drinking in women at risk for pregnancy and/or preventing unintended pregnancy. METHODS: The OST CHOICES Program was made culturally appropriate for American Indian women and implemented with 3 communities, 2 on the reservation and 1 off. Data on drinking, sexual activity, and contraception use were collected at baseline and 3 and 6 months postintervention. Data were analyzed using descriptive statistics, 1-way analysis of variance, and a random intercept generalized estimating equation model. RESULTS: A total of 193 nonpregnant American Indian women enrolled in the OST CHOICES Program, and all were at risk for AEP because of binge drinking and being at risk for an unintended pregnancy. Fifty-one percent of participants completed both 3- and 6-month follow-ups. Models showed a significant decrease in AEP risk from baseline at both 3- and 6-month follow-ups, indicating the significant impact of the OST CHOICES intervention. Women in the OST CHOICES Program were more likely to reduce their risk for AEP by utilizing contraception, rather than decreasing binge drinking. CONCLUSIONS: Even with minor changes to make the CHOICES intervention culturally and linguistically appropriate and the potential threats to program validity those changes entail, we found a significant impact in reducing AEP risk. This highlights the capacity for the CHOICES intervention to be implemented in a wide variety of settings and populations.

RESUMO

Objectives American Indian girls have higher teen pregnancy rates than the national rate. Intervention studies that utilize the Theory of Reasoned Action have found that changing attitudes and subjective norms often leads to subsequent change in a variety of health behaviors in young adults. The current study goal is to better understand sexual decision-making among American Indian youth using the Theory of Reasoned Action model and to introduce ways to utilize attitudes and subjective norms to modify risky behaviors. Methods The project collected qualitative data at a reservation site and an urban site through 16 focus groups with American Indian young people aged 16-24. Results Attitudes towards, perceived impact of, and perception of how others felt about teen pregnancy vary between American Indian parents and non-parents. Particularly, young American Indian parents felt more negatively about teen pregnancy. Participants also perceived a larger impact on female than male teen parents. Conclusions There are differences between American Indian parents and non-parents regarding attitudes towards, the perceived impact of, and how they perceived others felt about teen pregnancy. Teen pregnancy prevention programs for American Indian youth should include youth parents in curriculum creation and curriculum that addresses normative beliefs about teen pregnancy and provides education on the ramifications of teen pregnancy to change attitudes.

RESUMO

BACKGROUND: Long-acting reversible contraception (LARC) methods, including the intrauterine device (IUD) and the birth control implant, are the most effective form of prescribed birth control for pregnancy prevention. However, uptake of this highly effective form of birth control is slow. The purpose of this study was to explore use of the LARC methods in South Dakota women prescribed contraception and the importance of the provider in promoting this type of contraception. METHODS: This was a cross-sectional study of female patients who had been prescribed contraception at one of five locations in a South Dakota hospital system. Records were obtained through electronic health records for a six-month period. Descriptive analysis was performed using chi-square with counts and percentages. Logistic regression was used to determine differences in LARC prescriptions by patient age and provider title. RESULTS: A total of 2,174 individual patients were included in analysis. Of the 378 (17.4 percent) who were prescribed LARC methods, most (78.6 percent) were prescribed an IUD. Younger women (aged 11-19) were less likely to be prescribed LARCs compared to women aged 30-34. There were also significant differences in LARC prescriptions by provider type. Futhermore, we noted differences in LARC prescriptions for a provider who received a specific education and training on LARC from the American College of Obstetrics and Gynecology. CONCLUSIONS: There are many important factors to consider by the patient when choosing the most appropriate contraceptive method, including safety, effectiveness, accessibility, and affordability. Provider education may play an important role in promoting LARC methods.

RESUMO

In recently diverged gray treefrogs (Hyla chrysoscelis and H. versicolor), advertisement calls that differ primarily in pulse shape and pulse rate act as an important premating isolation mechanism. Temporally selective neurons in the anuran inferior colliculus may contribute to selective behavioral responses to these calls. Here we present in vivo extracellular and whole-cell recordings from long-interval-selective neurons (LINs) made during presentation of pulses that varied in shape and rate. Whole-cell recordings revealed that interplay between excitation and inhibition shapes long-interval selectivity. LINs in H. versicolor showed greater selectivity for slow-rise pulses, consistent with the slow-rise pulse characteristics of their calls. The steepness of pulse-rate tuning functions, but not the distributions of best pulse rates, differed between the species in a manner that depended on whether pulses had slow or fast-rise shape. When tested with stimuli representing the temporal structure of the advertisement calls of H. chrysoscelis or H. versicolor, approximately 27 % of LINs in H. versicolor responded exclusively to the latter stimulus type. The LINs of H. chrysoscelis were less selective. Encounter calls, which are produced at similar pulse rates in both species (≈5 pulses/s), are likely to be effective stimuli for the LINs of both species.

RESUMO

Interval-counting neurons (ICNs) respond after a threshold number of sound pulses have occurred with specific intervals; a single aberrant interval can reset the counting process. Female gray treefrogs, Hyla chrysoscelis and H. versicolor, discriminate against synthetic 'calls' possessing a single interpulse interval 2-3 three times the optimal value, suggesting that ICNs are important for call recognition. The calls of H. versicolor consist of pulses that are longer in duration, rise more slowly in amplitude and are repeated at a slower rate than those of H. chrysoscelis. Results of recordings from midbrain auditory neurons in these species include: (1) ICNs were found in both species and their temporal selectivity appeared to result from interplay between excitation and inhibition; (2) band-pass cells in H. versicolor were tuned to slower pulse rates than those in H. chrysoscelis; (3) ICNs that were selective for slow-rise pulse shape were found almost exclusively in H. versicolor, but fast-rise-selective neurons were found in both species, and (4) band-suppression ICNs in H. versicolor showed response minima at higher pulse rates than those in H. chrysoscelis. Selectivity of midbrain ICNs for pulse rise time and repetition rate thus correlate well with discriminatory abilities of these species that promote reproductive isolation.

RESUMO

Recent research concludes that prevention of alcohol-exposed pregnancies (AEP) must occur with preconceptional women, either by reducing alcohol consumption in women at-risk or planning pregnancy or preventing pregnancy in women drinking at risky levels. One AEP prevention program currently underway with non-pregnant American Indian women is the Oglala Sioux Tribe (OST) Changing High-risk alcohOl use and Increasing Contraception Effectiveness Study (CHOICES) Program. The OST CHOICES Program shows promise in lowering the AEP risk in American Indian women, and it is a natural next step to evaluate the potential impact that social support can have on further encouraging behavioral changes. Focus groups with community members and key informant interviews with health and social service professionals were completed. To uncover and interpret interrelated themes, a conventional content analysis methodology was used. Eight focus groups were held with 58 American Indian participants, including adult women of child-bearing age, elder women, and adult men. Key informant interviews were completed with 25 health and social service professionals. Based on input from the focus groups and key informant interviews, several subthemes regarding social support in the prevention of AEP stood out, including the role of family (especially elders), the impact community can have, and the important function of culture. In this study, we highlighted the important influence that social support can have on AEP prevention, especially among the American Indian population, where social support has cultural and historical significance.

RESUMO

Unintended pregnancies can have negative consequences for both mother and child. The focus of this study was to utilize perceived behavioral control measures (PBC; part of the theory of planned behavior) to identify relevant behavioral determinants of birth control use. This study also tested associations between direct and indirect PBC measures and intention of birth control use and between intention and birth control use. The methods included a randomly selected sample of patients at a health care system in the Upper Midwest who were sent a self-administered survey, with 190 non-pregnant women returning completed surveys. Participants indicated a high level of control over using birth control, and a significant positive correlation was observed between direct and indirect PBC measures. Participants also reported high intentions to use birth control, and a significant positive correlation was observed between intention and PBC. Additionally, both PBC measures and intention were independently and significantly associated with behavior, and PBC remained significantly associated with behavior when intention was added into the model. In conclusion, compared to the previous literature, this study is unique in that it examines indirect PBC measures and also the important role that PBC plays with actual birth control behavior.
