Contemporary principles of measure development for the
assessment of parenting [36, 37] guided the construction of the intrusiveness measure, including aggregating multiple measures of the same parenting behavior from different informants into a single composite measure; focusing on
specific behaviors (e.g., «mom gave me help
in putting on or taking off clothes») rather than vague concepts (e.g., «mom invades my privacy»); focusing on a short,
specific time -
frame; using items that are relevant to the age - group being studied; and including observational methods.
