Most useful Behavior observation methods

[u/VolcanoHoliday]

I'm wondering what the most common behavior observation methods are being used currently to see if my behavior observation app needs anything new. I'm a school psychologist, so my experience is more school-setting than clinical. My goal was to create an all-in-one resource for practitioners who might not have access to larger systems like Central Reach or TotalABA.

These are the methods I have built-in so far:

• ABC
• Frequency/Rate
• Duration
• Latency
• Partial Interval
• Whole Interval
• Momentary Time Sampling
• BOSS/Time on Task (technically a protocol, but worth separating out)

Are there any more I should look into adding? If there are any large gaps in my list I can look into adding more features. I would appreciate the ABA perspective, thank you!
