Abstract
The study investigated the impact of negotiation skills on marital conflict among secondary school teachers in Sokoto metropolis. It employed quasi-experimental design, consisting of one treatment group and one control group. Two research questions were posed, and two null hypotheses were formulated and tested at the 0.05 level of significance. The study population comprised 80 secondary school teachers, out of which a sample of 20 participants was purposively selected from 10 secondary schools within Sokoto metropolis. A 20-item researcher-developed questionnaire titled Marital Conflict Adjustment Instrument (MCAI) was used for data collection. The items were rated on a 5-point scale ranging from Always (1) to Never (5). Participants were divided into treatment groups (Negotiation Skills and SST) and a control group. The instrument was administered with the help of two trained teachers. Data analysis was carried out using means and standard deviation to answer the research questions, while ANCOVA was employed to test the hypotheses. The findings revealed that negotiation skills were effective in resolving marital conflicts among secondary school teachers. Consequently, it was recommended that couples be encouraged to adopt negotiation skills in resolving marital conflicts, as this would foster positive outcomes both in schools and in the wider society.
