Parental stress occurs when parenting demands are greater than the resources available to cope with parenting [1]. This negatively affects the overall functioning of the children and their parents, as stress negatively affects parents’ mental health and well-being, resulting in poor psychological and physical health [2–4]. Parental psychological stress may also affect their children’s well-being, that is, their psychological, health, and developmental outcomes. A distressed parent might not be actively engaged in stimulating interactions with their children, which increases the risk of maltreatment and adverse childhood experiences [5–8]. This makes it important to identify and address predictors of parental stress.
Previous research has identified a range of sociodemographic predictors of parental stress. Maternal characteristics such as household wealth, educational level, marital status, age, and the number of children under their care have been indicated as predictors of parental stress [9–13]. Poverty has been associated with poor mental health outcomes [13–15], and dealing with financial difficulties/hardships leads to high stress levels and negatively affects an individual's health [16]. Families living in poverty often face challenges such as inadequate financial and educational resources, food insecurity, relationship instability, and overall unpredictability [17, 18].
Lower education levels have also been shown to contribute to parenting stress [18]. However, other findings have also demonstrated higher parental stress among mothers with high education, and significantly lower parenting stress among mothers with intermediate education [11]. These findings could be attributed to the fact that even though education is related to greater resources, which could lead to less parental anxiety, it also facilitates alternative fulfilment, which may lead to a greater feeling of dissatisfaction with parenting [19]. In addition, it could also be attributed to ‘parents’ education anxiety’[20] that may result in experiences of tension, panic, worry, and other forms of negative emotions regarding whether their parenting practices positively affect their children’s developmental outcomes.
Regarding marital status, community support systems have been reported to lessen the parenting burden on mothers, especially support from their spouses [9]. Specifically, one study found that mothers reported that fathers’ involvement in parenting reduced the stressors that came with parenting [9]. Such findings have also been evident in other contexts, such as a study in the USA on mothers in low-income settings [21]. For mothers in low-income settings, marriage could be a great contributor to an improved household financial base, emotional support, and support in caring for the child(ren) [22]. Marriage quality can also contribute to stress and health outcomes [23].
Maternal age has also been reported as a predictor of parental stress. Specifically, mothers between 30 and 35 years of age reported less stress than mothers who were younger or older than this age[10]. In addition, the number of children under mothers’ care is also a predictor of parental stress, with mothers having more than one child below eight years reporting higher parental stress than those having one child [12]. These effects are particularly important for understanding contexts such as Kenya and Zambia, where the average number of children is estimated to be approximately four per family[24, 25]. However, limited evidence has explored these predictors in the sub-Saharan African (SSA) context, where factors such as the poverty index are very high compared with those in previous studies.
Using datasets from two previous studies conducted in Kenya and Zambia, we investigated the relationship between mothers’ demographic characteristics, such as age, income, education, marital status, number of children below five years of age, and parental stress level. The parental stress scale (aka parental stress scores, PSS) tool by Berry and Jones (1995) was used to obtain information from parents on their experience of undertaking day-to-day parental responsibility. This study aimed to investigate the association between mothers’ demographic characteristics and PSS scores.
