Developing a culturally appropriate video to promote dual-method use by urban teens: rationale and methodology

Strategies to improve adherence and continuation of shorter-term hormonal methods of contraception

BACKGROUND

Worldwide, hormonal contraceptives are among the most popular reversible contraceptives. Despite high perfect-use effectiveness rates, typical-use effectiveness rates for shorter-term methods such as oral and injectable contraceptives are much lower. In large part, this disparity reflects difficulties in ongoing adherence to the contraceptive regimen and low continuation rates. Correct use of contraceptives to ensure effectiveness is vital to reducing unintended pregnancy.

OBJECTIVES

To determine the effectiveness of strategies aiming to improve adherence to, and continuation of, shorter-term hormonal methods of contraception compared with usual family planning care.

SEARCH METHODS

We searched to July 2018 in the following databases (without language restrictions): The Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 7), PubMed via MEDLINE, POPLINE, Web of Science, ClinicalTrials.gov, and the International Clinical Trials Registry Platform (ICTRP).

SELECTION CRITERIA

We included randomized controlled trials (RCTs) comparing strategies aimed to facilitate adherence and continuation of shorter-term hormonal methods of contraception (such as oral contraceptives (OCs), injectable depot medroxyprogesterone acetate (DMPA or Depo-Provera), intravaginal ring, or transdermal patch) with usual family planning care in reproductive age women seeking to avoid pregnancy.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane. Primary outcomes were continuation or discontinuation of contraceptive method, rates of discontinuation due to adverse events (menstrual disturbances and all other adverse events), and adherence to method use as indicated by missed pills and on-time/late injections. Pregnancy was a secondary outcome.

MAIN RESULTS

We included 10 RCTs involving 6242 women. Six trials provided direct in-person counseling using either multiple counseling contacts or multiple components during one visit. Four trials provided intensive reminders of appointments or next dosing, of which two provided additional educational health information as well as reminders. All trials stated 'usual care' as the comparison.The certainty of the evidence ranged from very low to moderate. Main limitations were risk of bias (associated with poor reporting of methodological detail, lack of blinding, and incomplete outcome data), inconsistency, indirectness, and imprecision.Continuation of hormonal contraceptive methodsIt is uncertain whether intensive counseling improves continuation of hormonal contraceptive methods compared with usual care (OR 1.28, 95% CI 1.07 to 1.54; 2624 participants; 6 studies; I² = 79%; very low certainty evidence). The evidence suggested: if the chance of continuation with usual care is 39%, the chance of continuation with intensive counseling would be between 41% and 50%. The overall pooled OR suggested continuation of improvement, however, when stratified by contraceptive method type, the positive results were restricted to DMPA.It is uncertain whether reminders (+/- educational information) improve continuation of hormonal contraceptive methods compared with usual care (OR 1.33, 95% CI 1.03 to 1.73; 933 participants; 2 studies; I² = 69%; very low certainty evidence).The evidence suggested: if the chance of continuation with usual care is 52%, the chance of continuation with reminders would be between 52% and 65%.Discontinuation due to adverse eventsThe evidence suggested that counseling may be associated with a decreased rate of discontinuation due to adverse events compared with usual care, with a lower rate of discontinuation due to menstrual disturbances (OR 0.20, 95% CI 0.11 to 0.37; 350 participants; 1 study; low certainty evidence), but may make little or no difference to all other adverse events (OR 0.73, 95% CI 0.36 to 1.47; 350 participants; 1 study; low certainty evidence). The evidence suggested: if the chance of discontinuation with usual care due to menstrual disturbances is 32%, the chance of discontinuation with intensive counseling would be between 5% and 15%; and that if the chance of discontinuation with usual care due to other adverse events is 55%, the chance of discontinuation with intensive counseling would be between 30% and 64%.Discontinuation was not reported among trials that investigated the use of reminders (+/- educational information).Adherence Adherence was not reported among trials that investigated the use of intensive counseling.Among trials that investigated reminders (+/- educational information), there was no conclusive evidence of a difference in adherence as indicated by missed pills (MD 0.80, 95% CI -1.22 to 2.82; 73 participants; 1 study; moderate certainty evidence) or by on-time injections (OR 0.84, 95% CI 0.54 to 1.29; 350 participants; 2 studies; I² = 0%; low certainty evidence). The evidence suggested: if the chance of adherence to method use as indicated by on-time injections with usual care is 50%, the chance of adherence with method use as indicated by on-time injections with reminders would be between 35% and 56%.PregnancyThere was no conclusive evidence of a difference in rates of pregnancy between intensive counseling and usual care (OR 1.24, 95% CI 0.98 to 1.57; 1985 participants; 3 studies; I² = 0%, very low certainty evidence). The evidence suggested: if the chance of pregnancy with usual care is 18%, the chance of pregnancy with counseling would be between 18% and 25%.Pregnancy was not reported among trials that investigated the use of reminders (+/- educational information).

AUTHORS' CONCLUSIONS

Despite the importance of this topic, studies have not been published since the last review in 2013 (nine studies) with only one study added in 2019 that neither changed the results nor improved the certainty of evidence.Overall, the certainty of evidence for strategies to improve adherence and continuation of contraceptives is low. Intensive counseling and reminders (with or without educational information) may be associated with improved continuation of shorter-term hormonal contraceptive methods when compared with usual family planning care. However, this should be interpreted with caution due to the low certainty of the evidence. Included trials used a variety of shorter-term hormonal contraceptive methods which may account for the high heterogeneity. It is possible that the effectiveness of strategies for improving adherence and continuation are contingent on the contraceptive method targeted. There was limited reporting of objectively measurable outcomes (e.g. electronic monitoring device) among included studies. Future trials would benefit from standardized definitions and measurements of adherence, and consistent terminology for describing interventions and comparisons. Further research requires larger studies, follow-up of at least one year, and improved reporting of trial methodology.

Community Education and Engagement in Family Planning: Updated Systematic Review

CONTEXT

Community education and engagement are important for informing family planning projects. The objective of this study was to update two prior systematic reviews assessing the impact of community education and engagement interventions on family planning outcomes.

EVIDENCE ACQUISITION

Sixteen electronic databases were searched for studies relevant to a priori determined inclusion/exclusion criteria in high development settings, published from March 2011 through April 2016, updating two reviews that included studies from 1985 through February 2011.

EVIDENCE SYNTHESIS

Nine relevant studies were included in this updated review related to community education, in addition to 17 from the prior review. No new community engagement studies met inclusion criteria, as occurred in the prior review. Of new studies, community education modalities included mass media, print/mail, web-based, text messaging, and interpersonal interventions. One study on mass media intervention demonstrated a positive impact on reducing teen and unintended pregnancies. Three of four studies on interpersonal interventions demonstrated positive impacts on medium-term family planning outcomes, such as contraception and condom use. Three new studies demonstrated mostly positive, but inconsistent, results on short-term family planning outcomes.

CONCLUSIONS

Findings from this systematic review update are in line with a previous review showing the positive impact of community education using traditional modalities on short-term family planning outcomes, identifying additional impacts on long-term outcomes, and highlighting new evidence for education using modern modalities, such as text messaging and web-based education. More research is necessary to provide a stronger evidence base for directing community education and engagement efforts in family planning contexts.

Theory-based interventions for contraception

BACKGROUND

The explicit use of theory in research helps expand the knowledge base. Theories and models have been used extensively in HIV-prevention research and in interventions for preventing sexually transmitted infections (STIs). The health behavior field uses many theories or models of change. However, many educational interventions addressing contraception have no explicit theoretical base.

OBJECTIVES

To review randomized controlled trials (RCTs) that tested a theoretical approach to inform contraceptive choice and encourage or improve contraceptive use.

SEARCH METHODS

To 1 November 2016, we searched for trials that tested a theory-based intervention for improving contraceptive use in PubMed, CENTRAL, POPLINE, Web of Science, ClinicalTrials.gov, and ICTRP. For the initial review, we wrote to investigators to find other trials.

SELECTION CRITERIA

Included trials tested a theory-based intervention for improving contraceptive use. Interventions addressed the use of one or more methods for contraception. The reports provided evidence that the intervention was based on a specific theory or model. The primary outcomes were pregnancy and contraceptive choice or use.

DATA COLLECTION AND ANALYSIS

We assessed titles and abstracts identified during the searches. One author extracted and entered the data into Review Manager; a second author verified accuracy. We examined studies for methodological quality.For unadjusted dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). Cluster randomized trials used various methods of accounting for the clustering, such as multilevel modeling. Most reports did not provide information to calculate the effective sample size. Therefore, we presented the results as reported by the investigators. We did not conduct meta-analysis due to varied interventions and outcome measures.

MAIN RESULTS

We included 10 new trials for a total of 25. Five were conducted outside the USA. Fifteen randomly assigned individuals and 10 randomized clusters. This section focuses on nine trials with high or moderate quality evidence and an intervention effect. Five based on social cognitive theory addressed preventing adolescent pregnancy and were one to two years long. The comparison was usual care or education. Adolescent mothers with a home-based curriculum had fewer second births in two years (OR 0.41, 95% CI 0.17 to 1.00). Twelve months after a school-based curriculum, the intervention group was more likely to report using an effective contraceptive method (adjusted OR 1.76 ± standard error (SE) 0.29) and using condoms during last intercourse (adjusted OR 1.68 ± SE 0.25). In alternative schools, after five months the intervention group reported more condom use during last intercourse (reported adjusted OR 2.12, 95% CI 1.24 to 3.56). After a school-based risk-reduction program, at three months the intervention group was less likely to report no condom use at last intercourse (adjusted OR 0.67, 95% CI 0.47 to 0.96). The risk avoidance group (abstinence-focused) was less likely to do so at 15 months (OR 0.61, 95% CI 0.45 to 0.85). At 24 months after a case management and peer-leadership program, the intervention group reported more consistent use of hormonal contraceptives (adjusted relative risk (RR) 1.30, 95% CI 1.06 to 1.58), condoms (RR 1.57, 95% CI 1.28 to 1.94), and dual methods (RR 1.36, 95% CI 1.01 to 1.85).Four of the nine trials used motivational interviewing (MI). In three studies, the comparison group received handouts. The MI group more often reported effective contraception use at nine months (OR 2.04, 95% CI 1.47 to 2.83). In two studies, the MI group was less likely to report using ineffective contraception at three months (OR 0.31, 95% CI 0.12 to 0.77) and four months (OR 0.56, 95% CI 0.31 to 0.98), respectively. In the fourth trial, the MI group was more likely than a group with non-standard counseling to initiate long-acting reversible contraception (LARC) by one month (OR 3.99, 95% CI 1.36 to 11.68) and to report using LARC at three months (OR 3.38, 95% CI 1.06 to 10.71).

AUTHORS' CONCLUSIONS

The overall quality of evidence was moderate. Trials based on social cognitive theory focused on adolescents and provided multiple sessions. Those using motivational interviewing had a wider age range but specific populations. Sites with low resources need effective interventions adapted for their settings and their typical clients. Reports could be clearer about how the theory was used to design and implement the intervention.

Brief educational strategies for improving contraception use in young people

BACKGROUND

Global high rates of unplanned pregnancy and abortion among young women demonstrate the need for increased access to modern contraceptive services. In sub-Saharan Africa, the birth rate for those aged 15 to 19 years is 121 per 1000. In the USA, 6% of teens aged 15 to 19 years became pregnant in 2010. Most pregnancies among young women to age 25 are unintended.

OBJECTIVES

The aim was to identify brief educational interventions for improving contraceptive use among young people that are feasible for implementing in a clinic or similar setting with limited resources.

SEARCH METHODS

To 7 March 2016, we searched for studies in CENTRAL, PubMed, POPLINE, Web of Science, ClinicalTrials.gov and ICTRP.

SELECTION CRITERIA

We considered randomized controlled trials (RCTs) that assigned individuals or clusters as well as non-randomized studies (NRS). We included young people to age 25.The intervention had to be sufficiently brief for a clinic, i.e. one to three sessions of 15 to 60 minutes plus potential follow-up. The strategy had to emphasize one or more effective methods of contraception. Primary outcomes were pregnancy and contraceptive use.

DATA COLLECTION AND ANALYSIS

We assessed titles and abstracts identified during the searches. One author extracted and entered the data into Review Manager; a second author verified accuracy. We examined studies for methodological quality.For dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). For continuous variables, we computed the mean difference (MD) with 95% CI. We used adjusted measures for cluster RCTs, typically ORs, that the investigators reported. For NRS, which need to control for confounding, we also used reported adjusted measures. We did not conduct meta-analysis due to varied interventions and outcome measures.

MAIN RESULTS

We found 11 studies, published from 1983 to 2015, that included a total of 8338 participants. Ten were from the USA and one was from China. We focused here on intervention effects for our primary outcomes. Five studies showed some effect on contraceptive use. Of three RCTs that examined innovative counseling, one showed an intervention effect. At one year, adolescents with developmental counseling were more likely to use contraception effectively than those with standard counseling (OR 48.38, 95% CI 5.96 to 392.63).Three studies used an audiovisual tool plus counseling; two reported some effect on contraceptive use. An NRS with young men, aged 15 to 18, examined a slide-tape presentation plus reproductive health consultation. At one year, the intervention group was more likely than the standard-care group to report using an effective contraceptive and having a partner who used oral contraceptives (OCs), both at last intercourse (reported adjusted OR 1.51 and 1.66, respectively). Another study utilized a computer program for contraceptive decision-making plus standard counseling for women to age 20. At one year, fewer women in the intervention group at one site had not used OCs compared with the counseling-only group (3.4% versus 8.8%; reported P = 0.05).Three RCTs provided phone follow-up after counseling, one of which showed an effect on contraceptive use among women age 16 to 24. Women who received counseling plus phone calls to encourage contraceptive use were more likely than the counseling-only group to report consistent OC use at three months (OR 1.41, 95% CI 1.06 to 1.87) and six months (OR 1.39, 95% CI 1.03 to 1.87). Also at three months, they were more likely to report condom use at last sex (OR 1.45, 95% CI 1.03 to 2.03).Two cluster randomized trials trained providers on contraceptive methods and counseling. One trial with an intervention effect tested comprehensive contraceptive services for women to age 25, postabortion. At six months, the comprehensive-service group was more likely than the standard-care group to use an effective contraceptive (reported adjusted OR 2.03, 95% CI 1.04 to 3.98) and to use condoms consistently and correctly (reported adjusted OR 5.68, 95% CI 3.39 to 9.53).

AUTHORS' CONCLUSIONS

Few studies tested brief strategies for young people. We noted heterogeneity across studies in participants' ages and life situations. Of five studies with some effect, one provided moderate-quality evidence; four were older studies with low-quality evidence. More intensive strategies could be more effective, but would also be challenging for many clinics to implement.

Community Engagement in Family Planning in the U.S.: A Systematic Review

CONTEXT

Community engagement may include activities that involve community members in the design, implementation, and evaluation of services. The objective of this systematic review was to evaluate the evidence on this kind of community engagement in U.S. family planning programs, including its effects on various health outcomes, its perceived value, and the barriers and facilitators to implementation.

EVIDENCE ACQUISITION

Using an analytic approach drawn from U.S. Preventive Services Task Force, multiple databases were searched for articles published from 1985 through February 2011 that described studies about community engagement related to family planning. In 2011, relevant articles were reviewed, summarized, and assessed for potential bias using a standardized abstraction process. An updated, targeted review for the 2011-2014 period was conducted in early 2015.

EVIDENCE SYNTHESIS

Eleven papers related to family planning were included. All were qualitative, descriptive, and at high risk for bias. Engagement strategies involved various methods for developing educational materials, program development, or program evaluation. All studies reported benefits to community engagement, such as more-appropriate educational materials or more community support for programs. Barriers to engagement included the substantial time and resources required. Four more articles were identified in the targeted, additional search.

CONCLUSIONS

Community engagement is described as beneficial across the included studies, but the body of evidence for community engagement in family planning is relatively small. Given the high value ascribed to community engagement, more research and documentation of the various approaches taken and their relative strengths and weaknesses are needed.

Evaluating a Brief, Video-Based Sexual Risk Reduction Intervention and Assessment Reactivity with STI Clinic Patients: Results from a Randomized Controlled Trial

We report results from a randomized controlled trial designed to evaluate the efficacy of a video-based sexual risk reduction intervention and to measure assessment reactivity. Patients (N = 1010; 56 % male; 69 % African American) receiving care at a sexually transmitted infection (STI) clinic were assigned to one of four conditions formed by crossing assessment condition (i.e., sexual health vs. general health) with intervention condition (i.e., sexual risk reduction intervention vs. general health promotion). After completing their assigned baseline assessment, participants received their assigned intervention, and subsequently returned for follow-up assessments at 3, 6, 9, and 12 months. Participants in all conditions reduced their self-reported sexual risk behavior, and the incidence of new STIs declined from baseline through the follow-ups; however, there was no effect of intervention or assessment condition. We conclude that further risk reduction will require more intensive interventions, especially in STI clinics that already provide excellent clinical care.

Behavioral interventions for improving dual-method contraceptive use

BACKGROUND

Dual-method contraception refers to using condoms as well as another modern method of contraception. The latter (usually non-barrier) method is commonly hormonal (e.g., oral contraceptives) or a non-hormonal intrauterine device. Use of two methods can better prevent pregnancy and the transmission of HIV and other sexually transmitted infections (STIs) compared to single-method use. Unprotected sex increases risk for disease, disability, and mortality in many areas due to the prevalence and incidence of HIV/STI. Millions of women, especially in lower-resource areas, also have an unmet need for protection against unintended pregnancy.

OBJECTIVES

We examined comparative studies of behavioral interventions for improving use of dual methods of contraception. Dual-method use refers to using condoms as well as another modern contraceptive method. Our intent was to identify effective interventions for preventing pregnancy as well as HIV/STI transmission.

SEARCH METHODS

Through January 2014, we searched MEDLINE, CENTRAL, POPLINE, EMBASE, COPAC, and Open Grey. In addition, we searched ClinicalTrials.gov and ICTRP for current trials and trials with relevant data or reports. We examined reference lists of pertinent papers, including review articles, for additional reports.

SELECTION CRITERIA

Studies could be either randomized or non-randomized. They examined a behavioral intervention with an educational or counseling component to encourage or improve the use of dual methods, i.e., condoms and another modern contraceptive. The intervention had to address preventing pregnancy as well as the transmission of HIV/STI. The program or service could be targeted to individuals, couples, or communities. The comparison condition could be another behavioral intervention to improve contraceptive use, usual care, other health education, or no intervention.Studies had to report use of dual methods, i.e., condoms plus another modern contraceptive method. We focused on the investigator's assessment of consistent dual-method use or use at last sex. Outcomes had to be measured at least three months after the behavioral intervention began.

DATA COLLECTION AND ANALYSIS

Two authors evaluated abstracts for eligibility and extracted data from included studies. For the dichotomous outcomes, the Mantel-Haenszel odds ratio (OR) with 95% CI was calculated using a fixed-effect model. Where studies used adjusted analysis, we presented the results as reported by the investigators. No meta-analysis was conducted due to differences in interventions and outcome measures.

MAIN RESULTS

We identified four studies that met the inclusion criteria: three randomized controlled trials and a pilot study for one of the included trials. The interventions differed markedly: computer-delivered, individually tailored sessions; phone counseling added to clinic counseling; and case management plus a peer-leadership program. The latter study, which addressed multiple risks, showed an effect on contraceptive use. Compared to the control group, the intervention group was more likely to report consistent dual-method use, i.e., oral contraceptives and condoms. The reported relative risk was 1.58 at 12 months (95% CI 1.03 to 2.43) and 1.36 at 24 months (95% CI 1.01 to 1.85). The related pilot study showed more reporting of consistent dual-method use for the intervention group compared to the control group (reported P value = 0.06); the investigators used a higher alpha (P < 0.10) for this pilot study. The other two trials did not show any significant difference between the study groups in reported dual-method use or in test results for pregnancy or STIs at 12 or 24 months.

AUTHORS' CONCLUSIONS

We found few behavioral interventions for improving dual-method contraceptive use and little evidence of effectiveness. A multifaceted program showed some effect but only had self-reported outcomes. Two trials were more applicable to clinical settings and had objective outcomes measures, but neither showed any effect. The included studies had adequate information on intervention fidelity and sufficient follow-up periods for change to occur. However, the overall quality of evidence was considered low. Two trials had design limitations and two had high losses to follow up, as often occurs in contraceptive trials. Good quality studies are still needed of carefully designed and implemented programs or services.

Strategies to improve adherence and acceptability of hormonal methods of contraception

BACKGROUND

Worldwide, hormonal contraceptives are among the most popular reversible contraceptives. Despite their high theoretical effectiveness, typical use results in much lower effectiveness. In large part, this disparity reflects difficulties in adherence to the contraceptive regimen and low rates for long-term continuation.

OBJECTIVES

The intent was to determine the effectiveness of ancillary counseling techniques to improve adherence to, and continuation of, hormonal methods of contraception.

SEARCH METHODS

Through August 2013, we searched computerized databases for randomized controlled trials (RCTs) comparing client-provider interventions with standard family planning counseling. Sources included CENTRAL, MEDLINE, EMBASE, POPLINE, ClinicalTrials.gov and ICTRP. Earlier searches also included LILACS, PsycINFO, Dissertation Abstracts, African Index Medicus, and IMEMR.

SELECTION CRITERIA

We included RCTs of an intensive counseling technique or other client-provider intervention compared to routine family planning counseling. Interventions included group motivation; structured, peer, or multi-component counseling; and intensive reminders of appointments or next dosing. Outcome measures were discontinuation, reasons for discontinuation, number of missed pills or on-time injections, and pregnancy.

DATA COLLECTION AND ANALYSIS

One author evaluated the titles and abstracts from the searches to determine eligibility. Two authors extracted data from the included studies. We calculated the Mantel-Haenszel odds ratio (OR) for dichotomous outcomes. For continuous variables, the mean difference (MD) was computed; RevMan uses the inverse variance approach. For all analyses, 95% confidence intervals (CI) were also computed. Since the studies identified differed in both interventions and outcome measures, we did not conduct a meta-analysis.

MAIN RESULTS

Nine RCTs met our inclusion criteria. Five involved direct counseling; of those, two also provided multiple contacts by telephone. Four other trials provided intensive reminders, two of which also provided health education information. Three trials showed some benefit of the experimental intervention. In a counseling intervention, women who received repeated structured information about the injectable depot medroxyprogesterone acetate (DMPA) were less likely to discontinue the method by 12 months (OR 0.27; 95% CI 0.16 to 0.44) than women who had routine counseling. The intervention group was also less likely to discontinue due to menstrual disturbances (OR 0.20; 95% CI 0.11 to 0.37). Another trial showed a group with special counseling plus phone calls was more likely than the special-counseling group to report consistent use of oral contraceptives (OC) at 3 months (OR 1.41; 95% CI 1.06 to 1.87), though not at 12 months. The group with only special counseling did not differ significantly from those with standard care for any outcome. The third trial compared daily text-message reminders about OCs plus health information versus standard care. Women in the text-message group were more likely than the standard-care group to continue OC use by six months (OR 1.54; 95% CI 1.14 to 2.10). The text-message group was also more likely to avoid an interruption in OC use longer than seven days (OR 1.53; 95% CI 1.13 to 2.07).

AUTHORS' CONCLUSIONS

Only three trials showed some benefit of strategies to improve adherence and continuation. However, several had small sample sizes and six had high losses to follow up. The overall quality of evidence was considered moderate. The intervention type and intensity varied greatly across the studies. A combination of intensive counseling and multiple contacts and reminders may be needed to improve adherence and acceptability of contraceptive use. High-quality RCTs with adequate power and well-designed interventions could help identify ways to improve adherence to, and continuation of, hormonal contraceptive methods.

Theory-based interventions for contraception

BACKGROUND

The explicit use of theory in research helps expand the knowledge base. Theories and models have been used extensively in HIV-prevention research and in interventions for preventing sexually transmitted infections (STIs). The health behavior field uses many theories or models of change. However, educational interventions addressing contraception often have no stated theoretical base.

OBJECTIVES

Review randomized controlled trials (RCTs) that tested a theoretical approach to inform contraceptive choice; encourage contraceptive use; or promote adherence to, or continuation of, a contraceptive regimen.

SEARCH METHODS

Through June 2013, we searched computerized databases for trials that tested a theory-based intervention for improving contraceptive use (MEDLINE, POPLINE, CENTRAL, PsycINFO, ClinicalTrials.gov, and ICTRP). Previous searches also included EMBASE. For the initial review, we wrote to investigators to find other trials.

SELECTION CRITERIA

Trials tested a theory-based intervention for improving contraceptive use. We excluded trials focused on high-risk groups and preventing sexually transmitted infections or HIV. Interventions addressed the use of one or more contraceptive methods for contraception. The reports provided evidence that the intervention was based on a specific theory or model. The primary outcomes were pregnancy, contraceptive choice or use, and contraceptive adherence or continuation.

DATA COLLECTION AND ANALYSIS

The primary author evaluated abstracts for eligibility. Two authors extracted data from included studies. For the dichotomous outcomes, the Mantel-Haenszel odds ratio (OR) with 95% CI was calculated using a fixed-effect model. Cluster randomized trials used various methods of accounting for the clustering, such as multilevel modeling. Most reports did not provide information to calculate the effective sample size. Therefore, we presented the results as reported by the investigators. No meta-analysis was conducted due to differences in interventions and outcome measures.

MAIN RESULTS

We included three new trials for a total of 17. Ten randomly assigned individuals and seven were cluster-randomized. Eight trials showed some intervention effect.Two of 12 trials with pregnancy or birth data showed some effect. A theory-based group was less likely than the comparison group to have a second birth (OR 0.41; 95% CI 0.17 to 1.00) or to report a pregnancy (OR 0.24 (95% CI 0.10 to 0.56); OR 0.27 (95% CI 0.11 to 0.66)). The theoretical bases were social cognitive theory (SCT) and another social cognition model.Of 12 trials with data on contraceptive use (non-condom), six showed some effect. A theory-based group was more likely to consistently use oral contraceptives (OR 1.41; 95% CI 1.06 to 1.87), hormonal contraceptives (reported relative risk (RR) 1.30; 95% CI 1.06 to 1.58) or dual methods (reported RR 1.36; 95% CI 1.01 to 1.85); to use an effective contraceptive method (reported effect size 1.76; OR 2.04 (95% CI 1.47 to 2.83)) or use more habitual contraception (reported P < 0.05); and were less likely to use ineffective contraception (OR 0.56; 95% CI 0.31 to 0.98). Theories and models included the Health Belief Model (HBM), SCT, SCT plus another theory, other social cognition, and motivational interviewing (MI).For condom use, a theory-based group had favorable results in 5 of 11 trials. The main differences were reporting more consistent condom use (reported RR 1.57; 95% CI 1.28 to 1.94) and more condom use during last sex (reported results: risk ratio 1.47 (95% CI 1.12 to 1.93); effect size 1.68; OR 2.12 (95% CI 1.24 to 3.56); OR 1.45 (95% CI 1.03 to 2.03)). The theories were SCT, SCT plus another theory, and HBM.Nearly all trials provided multiple sessions or contacts. SCT provided the basis for seven trials focused on adolescents, of which five reported some effectiveness. Two others based on other social cognition models had favorable results with adolescents. Of six trials including adult women, five provided individual sessions. Some effect was seen in two using MI and one using the HBM. Two based on the Transtheoretical Model did not show any effect.

AUTHORS' CONCLUSIONS

Eight trials provided evidence of high or moderate quality. Family planning researchers and practitioners could adapt the effective interventions, although most provided group sessions for adolescents. Three were conducted outside the USA. Clinics and low-resource settings need high-quality evidence on changing behavior. Thorough use of single theories would help in identifying what works, as would better reporting on research design and intervention implementation.

Strategies to improve adherence and acceptability of hormonal methods of contraception

BACKGROUND

Worldwide, hormonal contraceptives are among the most popular reversible contraceptives in current use. Despite their high theoretical effectiveness, typical use results in much lower effectiveness. In large part, this disparity reflects difficulties in adherence to the contraceptive regimen and low rates for long-term continuation.

OBJECTIVES

To determine the effectiveness of ancillary techniques to improve adherence to, and continuation rates of, hormonal methods of contraception.

SEARCH STRATEGY

We searched computerized databases for randomized controlled trials (RCTs) comparing client-provider interventions with standard family planning counseling. Sources included CENTRAL, MEDLINE, EMBASE, POPLINE, LILACS, PsycINFO, ClinicalTrials.gov and ICTRP.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) of an intensive counseling technique or client-provider intervention versus routine family planning counseling. Interventions included group motivation; structured, peer, or multi-component counseling; and intensive reminders of appointments or next dosing. Outcome measures were discontinuation, reasons for discontinuation, number of missed pills and on-time injections, and pregnancy.

DATA COLLECTION AND ANALYSIS

The primary author evaluated all titles and abstracts from the searches to determine eligibility. Two authors independently extracted data from the included studies. With RevMan, we calculated the odds ratio for all dichotomous outcomes and the mean difference for continuous data. The studies were so different that we did not conduct a meta-analysis.

MAIN RESULTS

We found eight RCTs; only one showed a statistically significant benefit of the experimental intervention. In that trial, women who received repeated, structured information about the injectable contraceptive depo-medroxyprogesterone acetate (DMPA) were less likely to have discontinued the method by 12 months (OR 0.27; 95% CI 0.16 to 0.44) than were women who had routine counseling. The intervention group was also less likely to discontinue due to menstrual disturbances (OR 0.20; 95% CI 0.11 to 0.37). In another study, the intervention group was less likely to discontinue due to dissatisfaction with the contraceptive method (OR 0.61; 95% CI 0.38 to 0.98), but overall continuation was not affected.

AUTHORS' CONCLUSIONS

Most studies to date have shown no benefit of strategies to improve adherence and continuation. These trials have important limitations, however. Three had small sample sizes, four had high losses to follow up, and the intervention and its intensity varied across the studies. High-quality research is a priority, since adherence and continuation are fundamentally important to the successful use of hormonal contraceptives.

Theory-based interventions for contraception

BACKGROUND

The explicit use of theory in research helps expand the knowledge base. Theories and models have been used extensively in HIV-prevention research and in interventions for preventing sexually transmitted infections (STIs). The health behavior field uses many theories or models of change. However, educational interventions addressing contraception often have no stated theoretical base.

OBJECTIVES

Review randomized controlled trials (RCTs) that tested a theoretical approach to inform contraceptive choice; encourage contraceptive use; or promote adherence to, or continuation of, a contraceptive regimen.

SEARCH STRATEGY

We searched computerized databases for trials that tested a theory-based intervention for improving contraceptive use (MEDLINE, POPLINE, CENTRAL, PsycINFO, EMBASE, ClinicalTrials.gov, and ICTRP). We also wrote to researchers to find other trials.

SELECTION CRITERIA

Trials tested a theory-based intervention for improving contraceptive use. We excluded trials focused on high-risk groups and preventing sexually transmitted infections or HIV. Interventions addressed the use of one or more contraceptive methods for contraception. The reports provided evidence that the intervention was based on a specific theory or model. The primary outcomes were pregnancy, contraceptive choice, initiating or changing contraceptive use, contraceptive regimen adherence, and contraception continuation.

DATA COLLECTION AND ANALYSIS

The primary author evaluated abstracts for eligibility. Two authors extracted data from included studies. We calculated the odds ratio for dichotomous outcomes. No meta-analysis was conducted due to intervention differences.

MAIN RESULTS

Fourteen RCTs met our inclusion criteria. In 2 of 10 trials with pregnancy or birth data, a theory-based group showed better results. Four of 10 trials with contraceptive use data (other than condoms) showed better outcomes in an experimental group. For condom use, a theory-based group had favorable results in three of eight trials. Social Cognitive Theory was the main theoretical basis for five trials, of which three showed positive results. Two based on other social cognition models had favorable results, as did two of four focused on motivational interviewing. Thirteen trials provided multiple sessions or contacts. Of seven effective interventions, five targeted adolescents, including four with group sessions. Three effective trials had individual sessions. Seven trials were rated as having high or moderate quality; three of those had favorable results.

AUTHORS' CONCLUSIONS

Family planning researchers and practitioners could adapt the effective interventions. Reproductive health needs high-quality research on behavior change, especially for clinical and low-resource settings. More thorough use of single theories would help, as would better reporting on research design and intervention implementation.

Hooking up and sexual risk taking among college students: a health belief model perspective

"Hooking up" with friends, strangers, and acquaintances is a popular way for college students to experience sexual intimacy without investing in relationships. Because hooking up often occurs in situations in which prophylactics against sexually transmitted infections (STIs) are not available or in which students' judgment is impaired, it can involve risky behaviors that compromise student health. As such, in-depth studies of the factors related to sexual risk taking during hookups are needed, to advance preventive research and programming. Based on semistructured interviews with 71 college students about their hooking-up experiences, the findings of this study demonstrate that the Health Belief Model can serve as a useful framework for understanding sexual risk taking during hooking up, and offers suggestions for sexual risk-prevention programs on college campuses. The results demonstrate why students' assessments of their own and their peers' susceptibility to STIs are often misinformed. The findings also show how situational characteristics, such as spontaneity, undermine students' sexual self-efficacy.

A Linguistic Investigation of Mediators Between Religious Commitment and Health Behaviors in Older Adolescents

Social scientists are beginning to take an interest in the role that religiosity plays in the development of health behaviors throughout adolescence. Although there is mounting evidence of a relationship between these constructs, how and why such relationships exist is not well understood. In this exploratory study of 28 racially diverse university students, we examined whether the relationship between religious commitment and health behaviors could be detected through written language. The results indicated that religious commitment and various indices of healthy lifestyle practices were strongly correlated, that healthy lifestyle practices were related to use of causal words (representing cognitive attempts at understanding causes and effects) and first person plural words (representing social connectedness). The results were consistent with a model in which participants' use of causal words partially or fully mediated the relations between religious commitment and healthy lifestyle practices. Implications of findings and directions for future research are discussed.

The primary author evaluated abstracts for eligibility. Two authors extracted data from included studies. We calculated the odds ratio for dichotomous outcomes and the mean difference for continuous data. No meta-analysis was conducted due to intervention differences.

MAIN RESULTS

Of 26 trials, 12 interventions addressed contraception (other than condoms), while 14 focused on condom use for preventing HIV or STIs. In 2 of 10 trials with pregnancy or birth data, a theory-based group showed better results. Four of nine trials with contraceptive use (other than condoms) showed better outcomes in an experimental group. For condom use, a theory-based group had favorable results in 14 of 20 trials, but the number was halved in a subgroup analysis. Social Cognitive Theory was the main theoretical basis for 12 trials, and 10 showed positive results. Of the other 14 trials, favorable results were shown for other social cognition models (N=2), motivational interviewing (N=5), and the AIDS Risk Reduction Model (N=2). No major patterns were detected by type of theory, intervention, or target population.

AUTHORS' CONCLUSIONS

Family planning researchers and practitioners could apply the relevant theories and effective interventions from HIV and STI prevention. More thorough use of single theories would help inform the field about what works. Better reporting is needed on research design and intervention implementation.

Soap opera video on handheld computers to reduce young urban women's HIV sex risk

The purpose of this study was to develop a soap opera video, A Story about Toni, Mike, and Valerie, designed to communicate HIV risk reduction themes. The study evaluated viewing the video and responding to audio computer assisted self-interview (ACASI) on a handheld computer. The sample was 76 predominately African American women, aged 18-29, in sexual relationships with men. Data were collected in urban neighborhoods in the northeastern United States. A pretest-posttest control group design with systematic assignment indicated statistically significant reduction in expectations to engage in unprotected sex in the experimental group. The handheld computer was found to be acceptable to view the near feature length video and complete ACASI. To date, no study has reported on use of video and ACASI on a handheld device to reduce HIV risk. The significance is the potential to stream health promotion videos to personal devices, such as cell phones.

Safe in the city: developing an effective video-based intervention for STD clinic waiting rooms

There is a strong need for inexpensive, easily administered HIV and STD prevention interventions that are highly replicable and appealing to diverse clinic audiences. This article describes the four-step iterative and collaborative process used by the Safe City Study Group to design and develop a brief video-based intervention: Safe in the City. Step 1 involves identification of an appropriate intervention medium, a theoretical framework, and key messages; Step 2, collaboration with a film company to integrate the framework and key messages into an entertaining product; Step 3, facilitation of a multistep participatory process involving input from members of the priority audience (clinic patients), clinic staff, and community reviewers; and Step 4, pilot-testing to determine structural barriers to patients' viewing the video in clinic waiting rooms. Safe in the City has been demonstrated to reduce incident STDs among clinic patients in three cities in the United States.

Using culture-centered qualitative formative research to design broadcast messages for HIV prevention for African American adolescents

The need for formative research in designing mass media health-education messages is widely accepted; however, distinct methodologies for developing such messages are less well documented. This article describes a culture-centered approach for developing messages to promote sexual risk reduction in urban African American adolescents. The method uses qualitative formative research to identify "competing narratives" that support healthy behavior despite the dominance of messages that favor risk-taking behavior. The method is illustrated using qualitative analysis of semistructured interviews with 124 adolescents. Analysis focuses on two barriers to sexual risk reduction: (a) social pressure for early initiation of sexual intercourse and (b) perceptions that condoms reduce sexual pleasure. We demonstrate how competing narratives identified in the analysis can be featured in radio and television messages advocating healthy behavior by modeling risk-reducing negotiation skills.

Predictors of dual method use for pregnancy and HIV prevention among adolescent South African women

INTRODUCTION

Dual contraceptive method use is advocated for adolescent women to prevent pregnancy, sexually transmitted diseases and HIV.

METHODS

We examined data from a nationally representative sample of South African women aged 15-24 years to establish factors associated with dual method use.

RESULTS

Only 7% of current contraceptive users reported using dual methods, although this percentage increased to 28.1% when women reporting hormonal contraception and condom use at last sex were included. In multivariate analyses, having talked about condoms with a partner was most strongly associated with dual method use (adjusted odds ratio (AOR), 12.3; 95% confidence interval (CI), 6.1-25.1) and suggests that communication skills might be the most effective way of increasing dual method use. Difficulty in accessing condoms was associated with lower odds of dual method use (AOR, 0.5; 95% CI, 0.2-1.0).

CONCLUSION

We conclude with recommendations to increase male involvement and encourage communication between partners for the integration of HIV prevention and other reproductive health care services.

A brief, low-cost, theory-based intervention to promote dual method use by black and Latina female adolescents: a randomized clinical trial

HIV/AIDS disproportionately affects young women of color. Young women who use hormonal contraception are less likely to use condoms. Brief, inexpensive HIV-prevention interventions are needed for high-volume clinics. This study was a randomized clinical trial of two interventions: (a) a video made for this study and (b) an adaptation of Project RESPECT counseling. Four hundred Black and Latina teenage women completed a questionnaire about their sexual behaviors and were randomly assigned to (a) see the video, (b) get counseling, (c) see the video and get counseling, or (d) receive usual care. At 3-month follow-up, those who saw the video and received counseling were 2.5 times more likely to have used a condom at last intercourse with their main partner than teens in the usual care group. These differences did not persist at 12-month follow-up. This suggests that a brief intervention can positively affect condom use in the short term.

Strategies to improve adherence and acceptability of hormonal methods for contraception

BACKGROUND

Worldwide, hormonal contraceptives are among the most popular reversible contraceptives in current use. Despite their high theoretical effectiveness, typical use results in much lower effectiveness. In large part, this disparity reflects difficulties in adherence to the contraceptive regimen and low rates for long-term continuation.

OBJECTIVES

To determine the effectiveness of ancillary techniques to improve adherence to, and continuation rates of, hormonal methods of contraception.

SEARCH STRATEGY

We searched computerized databases for randomized controlled trials (RCTs) comparing client-provider interventions with standard family planning counseling. Sources included CENTRAL, MEDLINE, EMBASE, POPLINE, LILACS, and PsycINFO.

SELECTION CRITERIA

Randomized controlled trials (RCTs) of an intensive counseling technique or client-provider intervention versus routine family planning counseling. Interventions included group motivation; structured, peer, or multi-component counseling; and intensive reminders of appointments. Outcome measures were discontinuation, reasons for discontinuation, number of missed pills and on-time injections, and pregnancy.

DATA COLLECTION AND ANALYSIS

The primary author evaluated all titles and abstracts from the searches to determine eligibility. Two authors independently extracted data from the included studies. With RevMan 4.2, we calculated the odds ratio for all dichotomous outcomes and the weighted mean difference for continuous data. The studies were so different that we could not conduct a meta-analysis.

MAIN RESULTS

We found six RCTs; only one showed a statistically significant benefit of the experimental intervention. In that trial, women who received repeated, structured information about the injectable contraceptive depo-medroxyprogesterone acetate (DMPA) were less likely to have discontinued the method by 12 months (OR 0.27; 95% CI 0.16 to 0.44) than were women who had routine counseling. The intervention group was also less likely to discontinue due to menstrual disturbances. In another study, the intervention group was less likely to discontinue due to dissatisfaction with the contraceptive method, but overall continuation was not affected.

AUTHORS' CONCLUSIONS

Most studies to date have shown no benefit of strategies to improve adherence and continuation. These trials have important limitations, however. Two had small sample sizes, several had high losses to follow-up, and the intervention and its intensity varied across the studies. High-quality research is a priority, since adherence and continuation are fundamentally important to the successful use of hormonal contraceptives.

Strategies to prevent HIV transmission among heterosexual African-American women

BACKGROUND: African-American women are disproportionately affected by HIV, accounting for 60% of all cases among women in the United States. Although their race is not a precursor for HIV, the socioeconomic and cultural disparities associated with being African American may increase their risk of infection. Prior research has shown that interventions designed to reduce HIV infection among African-American women must address the life demands and social problems they encounter. The present study used a qualitative exploratory design to elicit information about strategies to prevent HIV transmission among young, low-income African-American women. METHODS: Twenty five low income African American women, ages 18-29, participated in five focus groups of five women each conducted at a housing project in Houston, Texas, a large demographically diverse metropolitan area that is regarded as one of the HIV/AIDS epicenters in the United States. Each group was audiotaped, transcribed, and analyzed using theme and domain analysis. RESULTS: The participants revealed that they had most frequently placed themselves at risk for HIV infection through drugs and drinking and they also reported drug and alcohol use as important barriers to practicing safer sex. The women also reported that the need for money and having sex for money to buy food or drugs had placed them at risk for HIV transmission. About one-third of the participants stated that a barrier to their practicing safe sex was their belief that there was no risk based on their being in a monogamous relationship and feeling no need to use protection, but later learning that their mate was unfaithful. Other reasons given were lack of concern, being unprepared, partner's refusal to use a condom, and lack of money to buy condoms. Finally, the women stated that they were motivated to practice safe sex because of fear of contracting sexually transmitted diseases and HIV, desire not to become pregnant, and personal experience with someone who had contracted HIV. CONCLUSION: This study offers a foundation for further research that may be used to create culturally relevant HIV prevention programs for African-American women.
