Insights
Nurses can effectively assess the level of infant motor development using the Structured Observation of Motor Performance in Infants (SOMP-I) tool. However, assessing the quality of motor performance requires further training for improved accuracy in early identification of motor disorders.
Area of Science:
- Pediatrics
- Nursing
- Developmental Pediatrics
Background:
- Early intervention is crucial for children with motor disorders.
- Nurses in the Swedish Child Health Service (CHS) play a vital role in child healthcare.
- Structured assessments can aid in identifying at-risk children.
Purpose of the Study:
- To evaluate nurses' ability to apply a structured assessment for early motor development.
- To determine if nurses can identify children at risk for motor disorders using a standardized tool.
Main Methods:
- The Structured Observation of Motor Performance in Infants (SOMP-I) tool was used.
- Fifty-five infants were assessed by nurses at three child health centers.
- Inter-rater reliability was assessed for both the level and quality of motor development.
Main Results:
- Excellent agreement was found for assessing the level of motor development (ICC 0.97-0.98).
- Agreement for the quality of motor performance was lower (ICC 0.02-0.46).
- Majority agreement was achieved when categorizing children by percentile for both level (78-82%) and quality (78-87%).
Conclusions:
- Nurses demonstrated excellent agreement in assessing the level of motor development with brief SOMP-I experience.
- Assessing the quality of motor performance requires further education and training for nurses.
- The applicability of SOMP-I as a standardized method for nurses in CHS warrants further research.
Rational, Aims And Objectives:
Increasing evidence highlights the importance of early interventions for motor disorders in children. Given the key medical role of the nurse within the Swedish Child Health Service (CHS), we aimed to examine if nurses could apply a structured assessment of early motor development at the child health centre to enable early identification of children at risk.
Methods:
Structured Observation of Motor Performance in Infants (SOMP-I) assesses infant's level of motor development and quality of motor performance using subscales converted to total scores. The total score for both level and quality can then be plotted within the SOMP-I percentile distribution at the child's age for comparison with a reference population. Fifty-five infants (girls: 30) were assessed according to SOMP-I at three child health centres. Assessments were performed by nurses (n = 10) in a clinical setting; one nurse performed the assessment while another nurse and a physiotherapist observed.
Results:
Agreement for the assessment of level as a continuous variable was excellent [intraclass correlation coefficient (ICC) 0.97-0.98], but was lower for quality (ICC 0.02-0.46). When the children were categorized according to the percentile range categories, the assessors were in agreement for the majority of the children, with respect to both level (78-82%) and quality (78-87%).
Conclusion:
Despite brief experience with SOMP-I, the agreement was excellent when assessing the level of motor development, but was less satisfactory for the assessment of quality of motor performance. More extensive education and training may be necessary to improve the nurses' ability to assess quality, as this domain was an entirely new concept to the nurses. Further research is warranted to determine the applicability of SOMP-I as a standardized method for nurses to assess motor development within the CHS.
