This type of robustness inspections are given about standard investigations statement (Leap one thousand Research People 2016)

C. Statistical Data

To examine system effects with the IPV and you may paths, the study exploited the usage of a cutoff endurance put on a continuous program qualification index (PMT rating) to recognize procedures and analysis groups. For this reason, email address details are legitimate on populace in the endurance and you may perform not show a complete shipping away from socioeconomic standing within the analysis communities. As an excellent discontinuity is employed on assignment of your own procedures, we be certain that the latest conditions that generally speaking need certainly to keep getting a routine regression discontinuity design way of be good within data, together with zero manipulation from the tolerance or expertise in brand new algorithm from the prospective beneficiaries so you’re able to dictate their qualification updates. The latest certified try regarding balance ranging from review and you will therapy teams try together with advertised for the current shot inside dining tables 2 and you can 3 (col. 10). On overall targeting get it done presented, the brand new PMT scores ranged out of ?3.294 to cuatro.601 z-results, during the assessment decide to try, the PMT scores include ?0.571 to help you 0.324 z-results, to the program qualifications cutoff at the ?0.106 z-score ( fundamental deviation = 0.thirty two ). six Households was basically systematically sampled within cutoff to possess investigations motives, and the ensuing home in the therapy decide to try is actually in this 0.46 practical deviations of your cutoff, and all sorts of review house are within 0.43 standard deviations of cutoff. Because of the small endurance of one’s shipping regarding tested homes around the latest PMT rating, an easy Performed was used to check the brand new impacts of your program: eight

Handle details included in the analysis provided personal- and you will family-height symptoms and you can neighborhood-height fixed effects. 8 In the individual peak, i managed getting many years (in years) and signs for all the certified training regarding one another girl and you can mate. nine Further, within the data of complete attempt, we control to be from inside the a polygamous commitment (reference group is actually nonpolygamous or, to own easier breakdown, an excellent monogamous union). Household-top control parameters provided domestic dimensions as well as the PMT rating. 10 I report the new means of all district signal variables during the descriptive balance and you will attrition dining tables; although not, once we tend to be people-level fixed outcomes, this type of evidence are not used in regression data (districts: East Mamprusi, Karaga, and you may Yendi throughout the Northern Area and Bongo and you may Garu Tempane on the Top East Area). To evaluate distinctions by the family design, we interact brand new sign to possess polygamous union into the procedures signal, time signal, and you will perception guess (undertaking a multiple telecommunications identity): eleven

D. Attrition

Attrition over the panel period has potential to threaten the internal validity and generalizability of the findings. BHM dating advice Overall attrition in our analytic sample is approximately 10%, slightly higher than the overall household sample rate of 6.6%, and does not vary significantly between treatment and comparison samples ( p -value = .35 using a simple t-test; Table 1). Further, we investigate whether the sample lost to follow-up differs significantly from our panel sample in terms of IPV outcomes, control variables, or pathway indicators (tables 2, 3). Column 7 shows the mean difference between the sample lost to follow-up in the treatment group, as compared with the same in the comparison group. Column 8 shows the p-value of this difference derived from a regression using treatment to predict the specific indicator, controlling for the PMT score and restricting to attritors. Table 2 shows that across 12 background characteristics and 14 pathway variables, only one is significant at the p < .05 level (there is a statistically significantly higher proportion of the treatment group lost to follow-up as compared with the comparison group in Bongo district). Table 3 shows that across 15 outcome indicators, the only ones to show evidence of differential attrition at p < .05 or lower are those measuring the frequency of sexual IPV (means of those lost to follow-up in the comparison group are slightly higher at .28 vs. the treatment group at .26). These results indicate that the potential for bias in overall findings due to attrition is low. Despite these promising results, we do find that women leaving our sample across both treatment arms differ in terms of background characteristics from those who remain in our sample (p-values shown in cols. 3 and 6). For example, women who leave the sample are generally younger, better educated, in monogamous partnerships (vs. polygamous), and live in smaller households. This may be reflective of rural-to-urban migration or other mobility patterns, although these differences are not generally observed for pathway variables, including indicators of economic standing.
