In the present study, no statistical differences were identified between anxiety, depression and stress levels between parents and caregivers of NSCL/P children and healthy children. However, the results discussion with those literature findings must be analyzed with caution.
Three studies [14–16] that used DASS-21 to measured psychological symptoms in NSCL/P children parents were founded. An Indian study [14], carried out with 50 NSCL/P children parents observed a positive association between the parents' stress and depression symptoms and the child's behavioral problems.
A second study, conducted in Belgium having 90 NSCL/P children parents parents [15] which, in addition to measuring psychological symptoms, also applied instruments to compare self-esteem and concerns about their social behavior. In the results, anxiety, depression and stress scores were normal, having no differences with other studies analyzed in the discussion. Moreover, higher anxiety scores only, were statistically associated with older parental age. Older parental age had association with depression and cleft postnatal diagnosis.
In Kumar et al. [16] study, there is a similarity in the methodology applied with our study, mainly due comparative group presence. Parents of CL/P adolescence (10 to 17 years) obtained a statistically significant association with higher levels of symptoms in the three dimensions measured by the DASS-21 (p < 0.001). Furthermore, there was a prevalence of severe and extremely severe depressive symptoms of 22.9% and 20%, respectively, in the group of CL/P children parents, while in the group of healthy children parents the prevalence was 1% and 2% for the same symptom ratings. Regarding anxiety in CL/P children parents group, extremely severe classification was 50% of prevalence, while in the control group the prevalence was 6.1%. As for the stress, severe symptoms were 21.4% in case group, and 1% in control.
As in the present study, two studies [17, 32] don’t showed association between anxiety and depression in the investigated groups. However, findings on the subject are diverse. There are publications in which parents of healthy children's scored more than NSCL/P caregivers [12, 33, 34], as well, contrary results [10, 13, 16, 35]. However, most of studies, symptoms levels were measured used different instruments.
Self-perceived parental stress is a constantly evaluated variable in studies with parents and caregivers of NSCL/P children [5, 6, 9, 10–13, 19, 33, 36]. Jeong et al. [33] showed that parents who had lower scores on the Beck's Anxiety and Depression Inventories had more stress. Furthermore, a reduction in the stress levels in NSCL/P children' parents with the passing of childhood is noted [6, 36]. Also, it's seen a correlation of these symptoms in the childs behavior [6, 33, 36].
Only two studies that measured psychological impacts in parents of NSCL/P childrens in Brazil was identified [11, 37]. First study was a cohort [11] that aimed analyzed parental stress in NSCL/P child parents before and after surgical procedures. This study found that stress levels used to progressively reduce after the intervention. Carvalho et al. [37] evaluated parents and caregivers emotions through of authors elaborate questionnaire. This one not showing anxiety, depression and/or stress symptoms, but feelings as fear, despair, sad and "shok" as more prevalent after cleft diagnosis.
Our study was the first to applied FC-19S in NSCL/P children parents. It was found that being a parent/caregiver was a protective factor in relation to parents/caregivers of healthy children. This finding remains apparently unexplained. However, it should be noted that some CL/P patients, in the pandemic, were assisted by teleorientation. This could be information that contributed to the fact that those NSCL/P children caregivers didn't feel impact generated by the pandemic more intensely and thus demonstrating less fear than the control group. Studies also evaluated fear of COVID-19 in healthy children parents [38, 39]. However, didn't used FC-19S [38] and another aimed fear and breastfeeding effectiveness associate [39]. This contribute to the importance verifying to fear od COVID-19 as an aggravating in family cycle mental health [38, 39].
Regarding groups features differences, NSCL/P children parents, compared to the control group, have higher OR in have a partner and have higher monthly income. There aren’t no results in the literature that explain this finding. However, it is necessary to point out that in Brazil, the treatment of CL/P is paid by the Unified Health Public System (SUS in Portuguese) [40]. Therefore regardless of the family members socioeconomic level, all patients with CL/P are treated in the same Specialized Centers.
Similar to the others studies [41–48] be female showed associations to anxiety and depression symptoms. Publications that infer that women have a higher OR in anxiety and depression symptoms development are based on many factors, mainly as physiological issues [43, 45, 48] and social demands [42, 43, 46, 47]. In addition, women historically seek more health services [44, 46] where surveys are carried out. Furthermore in COVID-19 pandemic had an increase in domestic violence case number [41], variable contributing the risk of mental disorders symptoms development.
Children's age (mean of 7.5 years) was associated with their parents' depression symptoms. This result differs from an Indian study [16] which parents of NSCL/P children over ten years old had greater scores in DASS-21 all dimension compared to parents of clinically healthy children and CL/P younger children. However, in a study carried out with caregivers of children [49], it was identified that mothers of younger children, regardless of the presence of disabilities or anomalies in their children, commonly present some anxiety, depression and stress levels.
Anxiety, depression and stress symptoms had strong association with severe fear of COVID-19. Thus, its able to infer that greater mental problems individuals are more afraid of COVID-19. Even though it is a relatively new scale, there are some studies [50–57] that used in conjunction FC-19S with the DASS-21. And also founded associations between fear of COVID-19 and higher scores of these symptoms [50–52, 54, 56, 57]. Furthermore there was strong correlation between instruments [51, 54, 57]. However, it should be noted that such association measures may changed over time. Because some studies emphasize that datas collection were carried out in the initial pandemic period or at virus infection waves peak [50–53, 55]. These factors may interfere in fear of COVID-19 scores witch has a psychological symptoms predilection. A differential of our study is that data collection was carried out over a year, thus, the participants experienced different pandemic phases, reducing possible bias regarding the high levels of fear of COVID-19.
There are some limitations that should be listed. As this is a convenience sampling study, the findings may be underreported, since the COVID-19 pandemic situation has led to changes in the health habits of individuals with greater mental health problems. Other limitation is due cross-sectional design of study which cannot measure the causality of parenting with the measured symptoms development.
